Configuration options for Storage.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

path: Option<PathBuf>

The path to the database. Defaults to db.bonsaidb if not specified.

memory_only: bool

Prevents storing data on the disk. This is intended for testing purposes primarily. Keep in mind that the underlying storage format is append-only.

unique_id: Option<u64>

The unique id of the server. If not specified, the server will randomly generate a unique id on startup. If the server generated an id and this value is subsequently set, the generated id will be overridden by the one specified here.

vault_key_storage: Option<Arc<dyn AnyVaultKeyStorage>>

The vault key storage to use. If not specified, LocalVaultKeyStorage will be used with the server’s data folder as the path. This is incredibly insecure and should not be used outside of testing.

For secure encryption, it is important to store the vault keys in a location that is separate from the database. If the keys are on the same hardware as the encrypted content, anyone with access to the disk will be able to decrypt the stored data.

default_encryption_key: Option<KeyId>

The default encryption key for the database. If specified, all documents will be stored encrypted at-rest using the key specified. Having this key specified will also encrypt views. Without this, views will be stored unencrypted.

workers: Tasks

Configuration options related to background tasks.

views: Views

Configuration options related to views.

key_value_persistence: KeyValuePersistence

Controls how the key-value store persists keys, on a per-database basis.

default_compression: Option<Compression>

Sets the default compression algorithm.

argon: ArgonConfiguration

Password hashing configuration.
