Configuration options for SqliteStore.

Fields

busy_timeout_ms: u64

Busy timeout in milliseconds for contended SQLite locks.

enable_wal: bool

Enable WAL journaling for file-backed databases.

synchronous_normal: bool

Set SQLite synchronous mode to NORMAL when applying default pragmas.

page_size_bytes: u32

Page size requested when creating a new SQLite database.

Existing databases retain the page size stored in their file header.

page_cache_size_bytes: u64

Maximum bytes retained in SQLite’s page cache for this connection.

A larger cache prevents dirty B-tree pages from being spilled and rewritten repeatedly during large prolly-node publications.

wal_autocheckpoint_pages: u32

Number of WAL pages that triggers an automatic checkpoint.

This should be large enough that a normal node publication commits without performing checkpoint I/O in its latency-sensitive path.

node_read_cache_size_bytes: usize

Maximum decoded node bytes retained by the adapter.

This cache complements SQLite’s encoded page cache and lets immutable nodes written earlier in the process satisfy later shared reads without another SQL lookup or decompression.

node_compression_min_bytes: usize

Minimum serialized node size considered for LZ4 compression.

Smaller values favor database size and cold I/O; larger values avoid compression CPU for latency-sensitive in-process publication.

mmap_size_bytes: u64

Maximum database bytes SQLite may access through memory-mapped reads.

This avoids per-page read syscalls for large immutable prolly nodes while retaining SQLite’s normal transactional and durability guarantees.
