ADMIN COMPACT

Description

This statement is used to trigger compaction for all replicas of a specified partition

Grammar:

ADMIN COMPACT TABLE table_name PARTITION partition_name WHERE TYPE='BASE/CUMULATIVE'

Explain:

1. This statement only means that the system attempts to submit a compaction task for each replica under the specified partition to compaction thread pool, and it is not guaranteed to be successful.
2. This statement supports executing compaction task for a single partition of the table at a time.

example

1. Attempt to trigger cumulative compaction for all replicas under the specified partition

ADMIN COMPACT TABLE tbl PARTITION par01 WHERE TYPE='CUMULATIVE';

2. Attempt to trigger base compaction for all replicas under the specified partition

ADMIN COMPACT TABLE tbl PARTITION par01 WHERE TYPE='BASE';
