# ADMIN COMPACT
|
|
## description
|
|
|
|
该语句用于对指定表分区下的所有副本触发一次Compaction
|
|
|
|
语法：
|
|
|
|
ADMIN COMPACT TABLE table_name PARTITION partition_name WHERE TYPE='BASE/CUMULATIVE'
|
|
|
|
说明：
|
|
|
|
1. 该语句仅表示让系统尝试将分区下每一个副本的compaction任务提交给compaction线程池，并不保证每一个副本的compaction任务都能成功执行。
|
|
2. 该语句每次只支持对表下的单个分区执行compaction。
|
|
|
|
## example
|
|
|
|
1. 对指定分区下的所有副本触发一次cumulative compaction
|
|
|
|
ADMIN COMPACT TABLE tbl PARTITION par01 WHERE TYPE='CUMULATIVE';
|
|
|
|
2. 对指定分区下的所有副本触发一次base compaction
|
|
|
|
ADMIN COMPACT TABLE tbl PARTITION par01 WHERE TYPE='BASE';
