# 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';
