Struct StorageConfig 

pub struct StorageConfig {
    pub data_dir: String,
    pub cache_bytes: u64,
    pub wal_checkpoint_bytes: u64,
    pub max_record_bytes: u64,
}

Storage engine settings.

Fields

data_dir: String

Directory for data files.

cache_bytes: u64

Bytes of decoded memory records the storage engine keeps in memory per open database. Each record is charged its encoded size (about 5 KB for a memory with a 1024 dimension embedding). A host with spare memory can set this to the database size so every scan after the first is served from memory instead of the file system.

wal_checkpoint_bytes: u64

The WAL is checkpointed (record file synced, record map persisted, log truncated) once it grows past this many bytes.

max_record_bytes: u64

Largest encoded memory record accepted; bigger writes fail with CapacityExceeded.
