Types

@Serializable

sealed interface Factory

Represents a factory interface for creating storage instances. The default implementation is InMemoryStorageFactory which stores data in memory

InMemoryStorageFactory

@Serializable

@SerialName(value = "!InMemory")

data class InMemoryStorageFactory(var epoch: Int = 0) : Storage.Factory

Default implementation for the storage module when configuring an XTDB node. Stores everything within in-process memory - a non-persistent option for storage.

LocalStorageFactory

@Serializable

@SerialName(value = "!Local")

data class LocalStorageFactory(val path: Path, var epoch: Int = 0) : Storage.Factory

Implementation for the storage module that persists data to the local file system, under the path directory.

RemoteStorageFactory

@Serializable

@SerialName(value = "!Remote")

data class RemoteStorageFactory(val objectStore: ObjectStore.Factory, var epoch: Int = 0) : Storage.Factory

Implementation for the storage module that persists data remotely within a specified objectStore,
