Struct PoolConfig 

pub struct PoolConfig {
    pub path: Option<PathBuf>,
    pub max_readers: usize,
    pub wal_mode: bool,
    pub busy_timeout: Duration,
    pub checkout_timeout: Duration,
    pub wal_autocheckpoint_pages: u32,
    pub journal_size_limit_bytes: i64,
}

Configuration for the connection pool.

Fields

path: Option<PathBuf>

Database path. None = in-memory (pool degrades to single connection).

max_readers: usize

Number of reader connections (default: min(num_cpus, 8)).

wal_mode: bool

WAL mode (must be true for pooling to work; default: true).

busy_timeout: Duration

Busy timeout per connection (default: 30s).

Overridable via KHIVE_BUSY_TIMEOUT_SECS.

checkout_timeout: Duration

Time to wait for a reader connection before returning an error (default: 5s).

Overridable via KHIVE_CHECKOUT_TIMEOUT_SECS.

wal_autocheckpoint_pages: u32

Number of WAL pages that triggers an automatic checkpoint.

Maps to PRAGMA wal_autocheckpoint. The default (4000 pages, ~16 MiB at SQLite’s default 4 KiB page size) matches the pre-config behaviour.

Overridable via KHIVE_WAL_AUTOCHECKPOINT_PAGES.

journal_size_limit_bytes: i64

Maximum WAL journal size in bytes before SQLite resets the WAL.

Maps to PRAGMA journal_size_limit. Default: 64 MiB.

Overridable via KHIVE_JOURNAL_SIZE_LIMIT_BYTES.
