Flink CDC首次全量同步几百万数据，状态后端增量方式的rocksdb，目前Checkpointed Data Size 基本接近Full Checkpoint Data Size大小，正常的吗？ck耗时也很长，请问可以从哪些方面优化优化？

Flink键控状态清理增量rocksdb检查点

Flink键控状态清理增量rocksdb检查点我有一个flink工作，可以在rocksdb后端保持大键控状态。我们正在使用增量检查点策略。随着时间的推移，状态的规模成为一个问题。我们检查了状态ttl解决方案，但它不支持增量的rocksdb状态。如果我真的需要增量检查点，那么这个问题的最佳方法是什么？
