Factory

@SerialName(value = "!Local")

@Serializable

data class Factory @JvmOverloads constructor(val path: Path, var instantSource: InstantSource = InstantSource.system(), var epoch: Int = 0, var useInstantSourceForNonTx: Boolean = false, var coroutineContext: CoroutineContext = Dispatchers.IO) : Log.Factory

Used to set configuration options for a local directory based XTDB Log.

Example usage, as part of a node config:

Xtdb.openNode {
   log = localLog(Path("test-path")) {
     instantSource = InstantSource.system()
   }
   ...
}
