From 9da2cf66a061a53376f6983e0ad8bf9caa8e6444 Mon Sep 17 00:00:00 2001 From: Ammar Arif Date: Fri, 20 Mar 2026 19:36:21 -0500 Subject: [PATCH 01/12] feat(db): add static file storage for immutable block/transaction data Introduce a static file storage layer for append-only, immutable block and transaction data. This moves heavy data (headers, transactions, receipts, traces, state updates) and sequential indexes (block hashes, tx hashes, body indices, tx blocks) to flat files, reducing MDBX write amplification for data that is never modified after insertion. Key changes: - New `static_files` module in katana-db with generic `StaticStore` trait (`FileStore` for production, `MemoryStore` for tests) - `FixedColumn` (O(1) lookup) and `IndexedColumn` (variable-size with .dat/.idx) abstractions for static data - `StaticFiles` container with typed read/write APIs using existing Compress/Decompress codecs - `Db` struct extended with `Arc>` - `DbProvider` updated to dual-write (static files + MDBX) with static-file-first reads and MDBX fallback - Sequential detection: only writes to static files when block numbers are sequential (production mode), falls back to MDBX-only for fork mode - Crash recovery via manifest-based truncation on startup - DB version bumped to 10 This is the initial scaffolding. A follow-up will move offset pointers into MDBX tables to ensure static file reads are gated by MDBX transaction snapshots for full ACID consistency.

charset=UTF-8 Content-Transfer-Encoding: 8bit Move offset pointers (.idx) into MDBX tables so all static file reads are gated by the MDBX transaction snapshot, ensuring ACID consistency. Key design changes: - New `StaticFileRef` enum stored as MDBX table value: `StaticFile { offset, length }` for production sequential writes, or `Inline(bytes)` for fork mode where static files aren't used - MDBX tables Headers, BlockStateUpdates, BlockBodyIndices, Transactions, Receipts, TxTraces now store `StaticFileRef` pointers instead of the actual data - `IndexedColumn` replaced by `DataColumn` (no .idx files) — the caller provides offset+length from MDBX when reading - Fixed-size index tables (BlockHashes, TxHashes, TxBlocks) kept in both MDBX and static files — MDBX serves as fallback for fork mode - Write path: append to static files → fsync → write pointers to MDBX → MDBX commit makes everything atomically visible - Read path: read pointer from MDBX snapshot → fetch data from static file (or decompress inline) — no data visible until MDBX commits - Manifest removed as authority — MDBX is the single source of truth - Crash recovery: MDBX state determines what exists, orphaned static file data is harmless (truncated on next startup) Co-Authored-By: Claude Opus 4.6 (1M context) --- bin/katana/src/cli/db/prune.rs | 12 +- crates/storage/db/src/models/mod.rs | 2 + crates/storage/db/src/models/receipt.rs | 25 +- crates/storage/db/src/models/state_update.rs | 21 +- .../storage/db/src/models/static_file_ref.rs | 129 +++++ crates/storage/db/src/static_files/column.rs | 158 ++---- crates/storage/db/src/static_files/segment.rs | 496 +++++++++--------- crates/storage/db/src/tables.rs | 127 ++--- .../provider/provider/src/providers/db/mod.rs | 433 ++++++++------- .../provider/src/providers/db/state.rs | 15 +- .../provider/src/providers/fork/mod.rs | 9 +- 11 files changed, 767 insertions(+), 660 deletions(-) create mode 100644 crates/storage/db/src/models/static_file_ref.rs diff --git a/bin/katana/src/cli/db/prune.rs b/bin/katana/src/cli/db/prune.rs index bae7ac84a..7e1f7527b 100644 --- a/bin/katana/src/cli/db/prune.rs +++ b/bin/katana/src/cli/db/prune.rs @@ -136,11 +136,15 @@ fn prune_database(db_path: &str, mode: PruneMode) -> Result<()> { Ok(()) } -/// Get the latest block number from the static files. +/// Get the latest block number from the MDBX Headers table. fn get_latest_block_number(db: &katana_db::Db) -> Result { - db.static_files() - .latest_block_number() - .context("Failed to read latest block number")?

charset=UTF-8 Content-Transfer-Encoding: 8bit Optimize the static file storage layer based on benchmark results: 1. **pread/pwrite**: Replace seek+read/write with pread/pwrite syscalls. Reads no longer need the mutex, writes use pwrite under a lightweight lock. Cached file length in AtomicU64 avoids fstat syscalls. 2. **mmap for reads**: Memory-map static files for zero-copy reads from the kernel page cache. Reads within the mapped region skip syscalls entirely. Falls back to pread for data written after the last remap. Remap is called on commit() to make new data visible. 3. **Remove redundant dual-writes**: BlockHashes, TxHashes, TxBlocks are only written to MDBX in fork (non-sequential) mode. In sequential mode, they exist only in static files, saving 3 MDBX puts per block. 4. **Move fsync out of insert_block_data**: Fsync no longer happens per block insert. Static files rely on MDBX's durability model — on crash, orphaned data is truncated to match MDBX state on next startup. 5. **Add file-backed benchmark**: New criterion benchmark measuring write and read performance with real disk I/O using tempdir-backed databases. Benchmark results (file-backed, vs MDBX-only baseline): - Reads: at parity or faster (latest_hash -19%, full_block -9%) - Writes: +21-27% overhead from dual-store architecture Co-Authored-By: Claude Opus 4.6 (1M context) --- Cargo.lock | 2 + crates/storage/db/Cargo.toml | 1 + crates/storage/db/src/static_files/column.rs | 8 + crates/storage/db/src/static_files/segment.rs | 20 ++ crates/storage/db/src/static_files/store.rs | 186 +++++++++++-- crates/storage/provider/provider/Cargo.toml | 5 + .../provider/provider/benches/static_files.rs | 253 ++++++++++++++++++ .../provider/provider/src/providers/db/mod.rs | 29 +- 8 files changed, 480 insertions(+), 24 deletions(-) create mode 100644 crates/storage/provider/provider/benches/static_files.rs diff --git a/Cargo.lock b/Cargo.lock index 0c6b75f90..db5e1ed53 100644 --- a/Cargo.lock +++ b/Cargo.lock @@ -6138,6 +6138,7 @@ dependencies = [ "katana-primitives", "katana-trie", "katana-utils", + "memmap2", "metrics", "page_size", "parking_lot", @@ -6608,6 +6609,7 @@ dependencies = [ "assert_matches", "auto_impl", "bitvec", + "criterion", "futures", "katana-chain-spec", "katana-contracts", diff --git a/crates/storage/db/Cargo.toml b/crates/storage/db/Cargo.toml index 9552d48c4..3447df4ef 100644 --- a/crates/storage/db/Cargo.toml +++ b/crates/storage/db/Cargo.toml @@ -16,6 +16,7 @@ indicatif = "0.17.8" cairo-lang-starknet-classes.workspace = true arbitrary = { workspace = true, optional = true } metrics.workspace = true +memmap2 = "0.9" page_size = "0.6.0" parking_lot.workspace = true roaring = { version = "0.10.3", features = [ "serde" ] } diff --git a/crates/storage/db/src/static_files/column.rs b/crates/storage/db/src/static_files/column.rs index ef6236e18..9eb1f7682 100644 --- a/crates/storage/db/src/static_files/column.rs +++ b/crates/storage/db/src/static_files/column.rs @@ -51,6 +51,10 @@ impl FixedColumn { self.store.sync() } + pub fn remap(&self) -> io::Result<()> { + self.store.remap() + } + /// Truncate to exactly `count` records. pub fn truncate_to(&self, count: u64) -> io::Result<()> { let new_len = count * self.record_size as u64; @@ -96,6 +100,10 @@ impl DataColumn { self.store.sync() } + pub fn remap(&self) -> io::Result<()> { + self.store.remap() + } + /// Truncate the data file to the given byte length. pub fn truncate(&self, byte_len: u64) -> io::Result<()> { self.store.truncate(byte_len) diff --git a/crates/storage/db/src/static_files/segment.rs b/crates/storage/db/src/static_files/segment.rs index 530cd3873..91f6821a9 100644 --- a/crates/storage/db/src/static_files/segment.rs +++ b/crates/storage/db/src/static_files/segment.rs @@ -305,6 +305,26 @@ impl StaticFiles { Ok(()) } + // ---- Remap ---- + + /// Refresh memory maps to cover all data written so far. + /// Call after a batch of writes to make new data visible via mmap reads. + /// This is lightweight (no fsync) — just updates the mmap pointers. + pub fn remap(&self) -> Result<(), StaticFileError> { + self.blocks.block_hashes.remap()?; + self.blocks.headers.remap()?; + self.blocks.block_body_indices.remap()?; + self.blocks.block_state_updates.remap()?; + + self.transactions.tx_hashes.remap()?; + self.transactions.tx_blocks.remap()?; + self.transactions.transactions.remap()?; + self.transactions.receipts.remap()?; + self.transactions.tx_traces.remap()?; + + Ok(()) + } + // ---- Crash recovery ---- /// Truncate static files to match MDBX-committed state. diff --git a/crates/storage/db/src/static_files/store.rs b/crates/storage/db/src/static_files/store.rs index 8383d0fce..2b6250847 100644 --- a/crates/storage/db/src/static_files/store.rs +++ b/crates/storage/db/src/static_files/store.rs @@ -1,6 +1,7 @@ use std::fs::{File, OpenOptions}; -use std::io::{self, Read, Seek, SeekFrom, Write}; +use std::io; use std::path::Path; +use std::sync::atomic::{AtomicU64, Ordering}; use parking_lot::{Mutex, RwLock}; @@ -16,11 +17,30 @@ pub trait StaticStore: Send + Sync + 'static { fn sync(&self) -> io::Result<()>; /// Truncate to the given length (for crash recovery). fn truncate(&self, len: u64) -> io::Result<()>; + /// Refresh any internal read caches (e.g., mmap) to cover newly-written data. + /// No-op by default. + fn remap(&self) -> io::Result<()> { + Ok(()) + } } -/// File-backed store (production). +/// File-backed store using `pread`/`pwrite` for concurrent I/O, with mmap for reads. +/// +/// - Reads use mmap when the data is within the mapped region, falling back to pread for data +/// written after the last remap. +/// - Writes use `pwrite` under a mutex for serialized appends. +/// - The mmap is refreshed on `remap()` to cover newly-written data. pub struct FileStore { - file: Mutex, + file: File, + path: std::path::PathBuf, + /// Serializes append writes. + write_lock: Mutex<()>, + /// Cached file length. + cached_len: AtomicU64, + /// Memory-mapped read view.

Write buffers are pre-sized based on the batch dimensions to avoid reallocations. Phase 2: Write ALL MDBX entries (pointers + indexes) in one pass. This groups B-tree inserts together for better cache locality. The batch method uses a single MDBX transaction for the entire chunk instead of per-block transactions, eliminating per-block tx overhead. Benchmark results (file-backed): - 100 blocks x 1 tx: per_block 12.0ms → batch 2.9ms (4.2x faster) - 100 blocks x 10 txs: per_block 30.3ms → batch 18.7ms (1.6x faster) - 100 blocks x 50 txs: per_block 105ms → batch 89.7ms (1.2x faster) - 500 blocks x 100 txs: per_block 1.12s → batch 907ms (1.2x faster) The batch method at 100x1tx (2.9ms) is 3.9x faster than the MDBX-only baseline (11.4ms) — the static file architecture pays off when batching.

After a crash, static files may contain orphaned data beyond what MDBX committed (since static file appends happen before MDBX commit). This orphaned tail data would cause subsequent appends to write at wrong offsets. Recovery reads the last committed pointer from each MDBX table (Headers, BlockStateUpdates, Transactions, Receipts, TxTraces) and truncates the corresponding .dat file to offset+length. Fixed-size columns (block_hashes, tx_hashes, tx_blocks) are truncated to the committed entry count. Called automatically in Db::new(), Db::open(), and Db::open_no_sync(). Skipped for Db::in_memory() (no crash to recover from).

Cannot be sequentially appended. | +| `TxNumbers` | Random-key reverse index (keyed by hash). Cannot be sequentially appended. | +| `BlockStatusses` | Mutable (finality status changes from AcceptedOnL2 to AcceptedOnL1). | +| `BlockHashes`, `TxHashes`, `TxBlocks` | Also in static files for sequential mode, but kept in MDBX as fallback for fork mode where static files are not written. | + +## MDBX as the Sole Authority + +**Critical invariant**: MDBX is the single source of truth for what data exists. + +- A reader opens an MDBX read transaction, which provides a consistent snapshot. +- All reads go through MDBX first: if the MDBX entry doesn't exist, the data doesn't exist. +- For `StaticFileRef::StaticFile` pointers, the reader fetches data from the `.dat` file + at the specified offset. This data is guaranteed to be on disk because it was written + *before* the MDBX transaction that committed the pointer. +- Static files have no independent index or manifest. They are raw data blobs addressed + solely by MDBX pointers. + +This means: +- **No stale reads**: A reader's MDBX snapshot determines exactly which static file data + is visible. Even if a concurrent writer has appended new data to the static files, the + reader won't see it because the MDBX pointers aren't in its snapshot. +- **No phantom reads**: If an MDBX pointer exists, the referenced data is guaranteed to + be durable in the static file (written and flushed before the MDBX commit). + +## Write Path + +### Sequential mode (production) + +Used when block numbers are sequential starting from the current static file count: + +``` +1. Append compressed data to .dat files (buffered pwrite, no fsync) + → returns (offset, length) for each variable-size entry +2. Append fixed-size entries (block_hash, tx_hash, tx_block) to their .dat files +3. Write MDBX entries: + - StaticFileRef::pointer(offset, length) for each variable-size table + - Direct values for BlockBodyIndices, BlockNumbers, BlockStatusses, TxNumbers +4. MDBX commit (caller calls provider.commit()) + - Static files remap (lightweight, updates mmap pointers for subsequent readers) +``` + +### Non-sequential mode (fork) + +Used when block numbers don't match the expected next static file position (e.g., fork +provider inserting blocks at arbitrary positions): + +``` +1. Compress data in memory +2. Write MDBX entries: + - StaticFileRef::inline(compressed_bytes) for each variable-size table + - Direct values for all other tables + - BlockHashes, TxHashes, TxBlocks also written to MDBX (no static file equivalent) +3. MDBX commit +``` + +### Batch mode (sync pipeline) + +`insert_block_data_batch()` provides a two-phase write optimized for inserting many +blocks in a single MDBX transaction: + +``` +Phase 1 — Static file appends (sequential I/O): + Pre-size write buffers based on batch dimensions. + For each block: append header, state_update, block_hash to static files. + For each tx: append transaction, receipt, trace, tx_hash, tx_block. + Collect all (offset, length) pointers in memory. + +Phase 2 — MDBX writes (B-tree inserts): + For each block: put Headers, BlockStateUpdates, BlockBodyIndices, BlockNumbers, etc. + For each tx: put Transactions, Receipts, TxTraces, TxNumbers. + For each block: put class artifacts, declarations. + +Commit: single MDBX transaction for the entire batch. +``` + +This separates sequential file I/O from random B-tree inserts, improving disk locality +and reducing MDBX transaction overhead (one tx instead of one per block). + +## Read Path + +All reads follow the same pattern: + +1. **MDBX lookup**: Read the table entry using the MDBX transaction snapshot. + - If not found → data doesn't exist, return `None`. +2. **Resolve `StaticFileRef`**: + - `StaticFile { offset, length }` → read from the `.dat` file via mmap (fast path) + or pread (fallback for recently-written data not yet remapped). + - `Inline(bytes)` → decompress directly from the MDBX value. +3. **Decompress**: Apply the same `Decompress` codec as the pre-static-files implementation. + +For fixed-size static file data (block_hashes, tx_hashes, tx_blocks), reads go directly +to the static file using `key * record_size` as the offset. These reads are gated by the +existence of a corresponding MDBX pointer entry (e.g., if `Headers(5)` exists, then +`block_hashes[5]` is guaranteed to exist in the static file). + +If the static file read returns `None` (e.g., fork mode where static files weren't written), +the read falls back to the MDBX table (BlockHashes, TxHashes, TxBlocks). + +## Crash Recovery + +### Why recovery is needed + +Static file appends happen **before** the MDBX transaction commits. This ordering is +required so that data is durable on disk before MDBX makes the pointers visible. But it +creates a window where a crash leaves orphaned data: + +``` +Timeline: + t0: Append block data to headers.dat ← data on disk (or in OS page cache) + t1: Append tx data to transactions.dat ← data on disk + t2: Write MDBX pointer entries ← in uncommitted MDBX transaction + t3: --- CRASH --- + t4: MDBX rolls back (automatic, ACID) ← pointers never committed + Static files still have data from t0-t1 ← ORPHANED +``` + +After restart: +- MDBX is clean (rolled back to last committed state). +- Static files have extra data at the tail that MDBX doesn't know about. +- `FileStore::open()` reads the actual file length, so `cached_len` includes the orphaned data. +- The next `append()` call would write at `cached_len` (past the orphaned data), producing + an offset that doesn't match the expected position. For fixed-size columns, the + `debug_assert!(expected_offset == actual_offset)` would fire. + +### How recovery works + +On every database open (`Db::new()`, `Db::open()`, `Db::open_no_sync()`), the +`recover_static_files()` function runs: + +1. Open an MDBX read transaction. +2. For each variable-size column (headers, state_updates, transactions, receipts, traces): + - Read the **last** entry from the corresponding MDBX table using a cursor. + - Extract `offset + length` from the `StaticFileRef::StaticFile` pointer. + - Truncate the `.dat` file to `offset + length` bytes. + - If the MDBX table is empty, truncate to 0. +3. For each fixed-size column (block_hashes, tx_hashes, tx_blocks): + - Determine the committed count from the last MDBX entry's key + 1. + - Truncate to `count * record_size` bytes. + +After truncation, `cached_len` matches the file length, and the next `append()` writes +at the correct position. + +### What recovery handles + +| Crash scenario | Static file state | MDBX state | Recovery action | +|---|---|---|---| +| During phase 1 (static file appends) | Partial data at tail | No uncommitted entries | Truncate to MDBX state (0 or previous commit) | +| During phase 2 (MDBX puts) | Complete data at tail | Uncommitted tx | Truncate tail (MDBX rolled back) | +| During MDBX commit | Complete data at tail | Committed or rolled back | If committed: no-op. If rolled back: truncate tail. | +| After MDBX commit, before remap | Complete data, stale mmap | Committed | No-op (data is consistent, remap happens on next open) | +| Clean shutdown | Consistent | Consistent | No-op (truncation is idempotent) | + +### What recovery does NOT handle + +- **MDBX corruption**: If MDBX itself is corrupted (disk failure, etc.), recovery cannot + proceed because it depends on reading MDBX state. This is an MDBX-level concern. +- **Static file corruption within committed range**: If a disk failure corrupts bytes + within the committed region of a `.dat` file, the data is silently corrupted. Recovery + only truncates the tail; it does not verify checksums within the committed range. + (This is the same as MDBX — neither system checksums individual values.) +- **Bit rot / silent data corruption**: Neither MDBX nor static files include per-record + checksums. Filesystem-level integrity (ZFS, Btrfs) is recommended for production. + +## FileStore Implementation + +### I/O strategy + +- **Reads**: Memory-mapped (`mmap`) for data within the mapped region. Zero-copy from the + kernel page cache — no syscall overhead. Falls back to `pread` for recently-appended data + not yet covered by the mmap. + +- **Writes**: Buffered `pwrite`. Small appends accumulate in an in-memory buffer (64KB + initial, auto-flush at 256KB). Flushed to disk as a single `pwrite` on `remap()` or + `sync()`. This reduces syscall count from ~54 per block (10 txs) to a handful per batch. + +- **No per-write fsync**: Static files rely on MDBX's durability model. On crash, orphaned + data is truncated by recovery. Explicit `sync()` is available for callers that need + stronger durability guarantees (e.g., before checkpoints). + +### Concurrency + +- `pread` is thread-safe (no shared file offset), so reads don't need a lock. +- `mmap` reads use a `RwLock` (shared access for reads, exclusive for remap). +- Writes use a `Mutex` to serialize appends and protect the write buffer. +- `cached_len` is an `AtomicU64` to avoid `fstat` syscalls on every access. + +### Remap + +After writes, the mmap doesn't cover the new data (it was created with the old file length). +`remap()` flushes the write buffer and creates a new mmap covering all data. This is called +automatically on `commit()` so subsequent readers see the new data through mmap. + +## Assumptions + +1. **Blocks are inserted sequentially in production mode.** Block numbers must equal the + current static file entry count. Non-sequential insertion (fork mode) falls back to + inline MDBX storage. + +2. **Blocks are never deleted or modified after insertion.** The static files are + append-only. There is no mechanism to update or remove individual entries. Reorgs are + not supported by this storage layer. + +3. **Single writer at a time.** Only one MDBX write transaction can be active, and static + file appends are serialized by the write lock. Concurrent readers are safe. + +4. **Recovery runs before any writes.** The `recover_static_files()` call in every `Db` + constructor ensures orphaned data is truncated before the first append. + +5. **MDBX is always openable after a crash.** MDBX's ACID properties guarantee this. + Static file recovery depends on being able to read the MDBX state. + +6. **File system preserves write ordering within a file.** `pwrite` to a file followed by + another `pwrite` to the same file is expected to be visible in order. This is guaranteed + by POSIX and all major file systems. + +7. **Inline mode produces identical data.** `StaticFileRef::Inline` stores the same + compressed bytes that `StaticFileRef::StaticFile` would reference in the `.dat` file. + Readers use the same `Decompress` codec for both cases. + +## Directory Layout + +``` +db/ +├── mdbx.dat MDBX database (pointers + indexes + mutable state) +├── mdbx.lck MDBX lock file +├── db.version Database version (currently 10) +└── static/ + ├── blocks/ + │ ├── headers.dat Variable-size, compressed VersionedHeader + │ ├── block_hashes.dat Fixed 32 bytes per entry + │ └── block_state_updates.dat Variable-size, compressed StateUpdateEnvelope + └── transactions/ + ├── transactions.dat Variable-size, compressed TxEnvelope + ├── receipts.dat Variable-size, compressed ReceiptEnvelope + ├── tx_traces.dat Variable-size, compressed TypedTransactionExecutionInfo + ├── tx_hashes.dat Fixed 32 bytes per entry + └── tx_blocks.dat Fixed 8 bytes per entry +``` From 6edd8511f01a6d169150f854083a7a8811453f48 Mon Sep 17 00:00:00 2001 From: Ammar Arif Date: Sat, 21 Mar 2026 17:42:24 -0500 Subject: [PATCH 10/12] docs(db): add inline documentation across static files codebase Add comprehensive doc comments to all public types, traits, methods, and key invariants in the static files storage layer: - StaticStore trait: append-only contract, error behavior, sync/remap semantics - FileStore: invariants for cached_len, mmap_len, write buffer relationship - FixedColumn/DataColumn: constructor contracts, sync/remap/reserve docs - StaticFiles segments: corrected field docs (BlockBodyIndices stored in MDBX, not via pointer), sequential vs fork mode explanation - StaticFileRef enum: role description, MDBX authority gate invariant - Db struct: combined MDBX + static files architecture, recovery model - insert_block_data: sequential vs fork mode documentation - resolve_static_ref: inline fallback explanation - Fixed Db::open/open_ro to use /// doc comments instead of // - Removed unused `path` field from FileStore and unused import in recovery Co-Authored-By: Claude Opus 4.6 (1M context) --- crates/storage/db/src/lib.rs | 11 +++- .../storage/db/src/models/static_file_ref.rs | 9 ++- crates/storage/db/src/static_files/column.rs | 12 ++++ crates/storage/db/src/static_files/mod.rs | 8 +++ crates/storage/db/src/static_files/segment.rs | 55 ++++++++++++++----- crates/storage/db/src/static_files/store.rs | 45 +++++++++++---- .../provider/provider/src/providers/db/mod.rs | 26 +++++++-- 7 files changed, 132 insertions(+), 34 deletions(-) diff --git a/crates/storage/db/src/lib.rs b/crates/storage/db/src/lib.rs index 56234cdae..9621575b7 100644 --- a/crates/storage/db/src/lib.rs +++ b/crates/storage/db/src/lib.rs @@ -35,6 +35,12 @@ use version::{ const GIGABYTE: usize = 1024 * 1024 * 1024; const TERABYTE: usize = GIGABYTE * 1024; +/// Database handle combining MDBX (authoritative index) with static files (bulk data store). +/// +/// MDBX stores pointers ([`StaticFileRef`]) into flat `.dat` files for heavy immutable data +/// (headers, transactions, receipts, traces, state updates), plus all mutable state, indexes, +/// and small values directly.

Existing constructors (open, open_ro, open_no_sync) preserved for backward compatibility.
