flink中checkpoint、io_tmp、rocksdb目录下会产生非常多的hardlink

1.flink中checkpoint、io_tmp、rocksdb目录下会产生非常多的hardlink引用，会有什么影响吗？2.io_tmp文件占用空间随时间越久会越占越大，有自动清理文件释放空间的机制吗？

大佬们，Flink中checkpoint设置为RocksDB，怎么定期清理老的checkpoint？

大佬们，Flink中checkpoint设置为RocksDB，怎么定期清理老的checkpoint数据啊，防止磁盘占满？放本机磁盘上了，我看flink1.17里，有个state.checkpoints.num-retained这个配置，是不是配置这个属性也可以啊
