# ADMIN REPAIR
|
|
## description
|
|
|
|
该语句用于尝试优先修复指定的表或分区
|
|
|
|
语法：
|
|
|
|
ADMIN REPAIR TABLE table_name[ PARTITION (p1,...)]
|
|
|
|
说明：
|
|
|
|
1. 该语句仅表示让系统尝试以高优先级修复指定表或分区的分片副本，并不保证能够修复成功。用户可以通过 ADMIN SHOW REPLICA STATUS 命令查看修复情况。
|
|
2. 默认的 timeout 是 14400 秒(4小时)。超时意味着系统将不再以高优先级修复指定表或分区的分片副本。需要重新使用该命令设置。

|
