set_auto_file_sync(GenServer.server(), boolean()) :: :ok

Configures whether to automatically force file sync upon each write operation.

If set to false, no automatic file sync is performed. That improves write performance, but leaves to the operative system the decision of when to flush disk buffers. This means that there is the possibility that recent writes might not be durable in case of a sudden machine shutdown. In any case, atomicity of multi operations is preserved, and partial writes will not corrupt the database.

If set to true, the file buffer will be forced to flush upon every write operation, ensuring durability even in case of sudden machine shutdowns, but decreasing write performance.
