1. 解决方法

被锁住的表为table，可以考虑复制一张ddl相同的表table_1，将数据复制到新表，再改名

sql 复制代码

insert into table_1 select * from table;
rename table to table_2 on cluster clickhouse_cluster;
rename table_1 to table on cluster clickhouse_cluster;
drop table table_2 on cluster clickhouse_cluster;

2. 查看只读表

sql 复制代码

select table,zookeeper_path,replica_path from `system`.replicas where is_readonly
