-And now you can configure them by setting key-value options in `TableConfig`, see [Fault Tolerance]({% link ops/config.zh.md %}#fault-tolerance), [State Backends]({% link ops/config.zh.md %}#checkpoints-and-state-backends) and [Checkpointing]({% link ops/config.zh.md %}#checkpointing) for more details.
