功能描述

系统租户下展示所有租户各个 Zone 的合并信息。

字段说明

字段名称	类型	是否可以为 NULL	描述
TENANT_ID	bigint(20)	NO	租户 ID
ZONE	varchar(128)	NO	Zone 名称
BROADCAST_SCN	bigint(20) unsigned	NO	广播的合并版本号
LAST_SCN	bigint(20) unsigned	NO	上一次合并的版本号
LAST_FINISH_TIME	timestamp(6)	NO	上一次合并结束时间
START_TIME	timestamp(6)	NO	合并开始时间
STATUS	varchar(10)	NO	`IDLE`：没有在合并中 `COMPACTING`：正在合并中

查询示例

系统租户查询所有租户各个 Zone 的合并信息。

obclient [oceanbase]> SELECT * FROM oceanbase.CDB_OB_ZONE_MAJOR_COMPACTION;
