ADMIN SET PARTITION VERSION

ADMIN SET PARTITION VERSION sets a partition to a specific data version.

Note that manually setting the partition version is a high-risk operation and is recommended only when problems occur in the cluster metadata. In normal circumstances, the version of a partition is consistent with that of the tablets within.

tip

This operation requires the SYSTEM-level OPERATE privilege. You can follow the instructions in GRANT to grant this privilege.

Syntax​

ADMIN SET TABLE <table_name> PARTITION ( <partition_name> | <partition_id> ) 
VERSION TO <version>

Parameters​

  • table_name: The name of the table to which the partition belongs.
  • partition_name: The name of the partition. You need to specify a partition using either partition_name or partition_id. For non-partitioned tables, partition_name is the same as the table name.
  • partition_id: The ID of the partition. You need to specify a partition using either partition_name or partition_id. For tables with the random bucketing strategy, you can only use partition_id to specify the partition.
  • version: The version you want to set for the partition.

Examples​

  1. Set the version of the non-partitioned table t1 to 10.

    ADMIN SET TABLE t1 PARTITION(t1) VERSION TO 10;

  2. Set the version of partition p1 in table t2 to 10.

    ADMIN SET TABLE t2 PARTITION(p1) VERSION TO 10;

  3. Set the version of the partition whose ID is 123456 to 10. t3 is a table with the random bucketing strategy.

    ADMIN SET TABLE t3 PARTITION('123456') VERSION TO 10;
