Struct SqliteTuning 

pub struct SqliteTuning {
    pub mmap_size: i64,
    pub page_size: i64,
    pub cache_size_kb: i64,
    pub busy_timeout_ms: u64,
    pub journal_size_limit: i64,
}

Tunable SQLite pragmas applied when opening the database. page_size and auto_vacuum only take effect on a freshly-created database (they are fixed once the file has content); the rest apply on every open. Defaults target a Linux host (4 KiB pages match the OS page / filesystem block size).

Fields

mmap_size: i64

PRAGMA mmap_size in bytes.

page_size: i64

PRAGMA page_size in bytes (fresh DB only). Must be a power of two.

cache_size_kb: i64

PRAGMA cache_size magnitude in KiB (applied as the negative form).

busy_timeout_ms: u64

PRAGMA busy_timeout in milliseconds.

journal_size_limit: i64

PRAGMA journal_size_limit in bytes.
