正常业务DDL变更(只有创建索引)时报错，问题现象跟这个 PD扩缩容成功后，执行create index语句报错ERROR 1105 (HY000): DDL job rollback, error报错一样，经和使用方沟通后，在业务低谷时段执行reload操作
执行tiup cluster reload cluster_name时报

这个节点之前开启过[rocksdb.titan] enabled = true，后来发现磁盘空间不均衡(TiKV存储目录不均衡)然后就把titan关闭了，并重启了这个tikv节点，看监控也在减少，但是很慢，如何查看这些blob数据都属于哪些表，针对单个表做compact操作
