Struct PoolConfig 

pub struct PoolConfig {
    pub base_path: String,
    pub lock_shards: usize,
}

Pool configuration for multi-database sharding.

When nested inside Config, enables DatabasePool to manage lazily-opened shard databases that share the parent config’s PRAGMAs and migrations.

Fields

base_path: String

Directory where shard databases are stored. Each shard creates {base_path}/{shard_name}.db.

lock_shards: usize

Number of internal lock shards for the connection map. Controls lock contention parallelism, not the number of tenant databases.
