Struct DbOptions 

pub struct DbOptions {
    pub create_if_missing: bool,
    pub memtable_flush_threshold: usize,
    pub edge_uniqueness: bool,
    pub compact_after_n_flushes: u32,
    pub wal_sync_mode: WalSyncMode,
    pub memtable_hard_cap_bytes: usize,
}

Options for opening a database.

Fields

create_if_missing: bool

memtable_flush_threshold: usize

edge_uniqueness: bool

compact_after_n_flushes: u32

Trigger compaction automatically after this many flushes. 0 = disabled.

wal_sync_mode: WalSyncMode

WAL sync mode. Default: WalSyncMode::GroupCommit.

memtable_hard_cap_bytes: usize

Hard cap on memtable size in bytes. When the memtable reaches this size, writes trigger a synchronous flush before proceeding. 0 = disabled. Should be >= memtable_flush_threshold when both are non-zero. Note: batch operations check backpressure once before writing; a single large batch may temporarily exceed the cap.
