请问 Paimon 的原子性更新依赖 catalog 的锁吗？我看这里的 lock.enabled 默认是 false，这个配置具体起什么作用呢？

Paimon’s snapshot management supports writing with multiple job writers.
For S3-like object store, its 'RENAME' does not have atomic semantic. We need to configure Hive metastore and enable 'lock.enabled' option for the catalog.
