ADMIN-SET-CONFIGβ
Nameβ
ADMIN SET CONFIG
Descriptionβ
This statement is used to set the configuration items of the cluster (currently only supports setting FE configuration items).
The configurable items can be viewed using the SHOW FRONTEND CONFIG;
command.
Syntax:
ADMIN SET FRONTEND CONFIG ("key" = "value") [ALL];
-- or
ADMIN SET ALL FRONTENDS CONFIG ("key" = "value");
Explanation
- Starting from versions 2.0.11 and 2.1.5, the
ALL
keyword is supported. When using theALL
keyword, the configuration parameters will be applied to all FEs (except for themaster_only
parameter). - This syntax does not persistently modify the configuration. After an FE restarts, the modified configuration becomes invalid. To persist the changes, the configuration items need to be synchronously added in fe.conf.
Exampleβ
Set
disable_balance
to trueADMIN SET FRONTEND CONFIG ("disable_balance" = "true");
