Struct Config 

pub struct Config {
    pub shard_count: usize,
    pub data_dir: Option<PathBuf>,
    pub wal_sync: SyncPolicy,
}

Configuration for opening an embedded Database.

The default configuration sets shard_count to the number of available hardware threads, which is a good starting point for most workloads.

Fields

shard_count: usize

Number of shard worker threads to spawn.

Each shard owns an independent key-space partition and runs on its own OS thread, so this value controls both parallelism and memory partitioning.

data_dir: Option<PathBuf>

Optional data directory for persistence. When set, WAL and RDB snapshots are stored under {data_dir}/shard-{N}/. Data is recovered automatically on startup.

wal_sync: SyncPolicy

WAL sync policy (only used when data_dir is set).
