SetShardTabletControl

vtctldclient SetShardTabletControl #

Sets the TabletControl record for a shard and tablet type. Only use this for an emergency fix or after a finished MoveTables.

Synopsis #

Sets the TabletControl record for a shard and tablet type.

Only use this for an emergency fix or after a finished MoveTables.

Always specify the denied-tables flag for MoveTables, but never for Reshard operations.

To set the DisableQueryService flag, keep denied-tables empty, and set --disable-query-service to true or false. This is useful to fix Reshard operations gone wrong.

To change the list of denied tables, specify the --denied-tables parameter with the new list. This is useful to fix tables that are being blocked after a MoveTables operation.

To remove the ShardTabletControl record entirely, use the --remove flag. This is useful after a MoveTables has finished to remove serving restrictions.

vtctldclient SetShardTabletControl [--cells=c1,c2...] [--denied-tables=t1,t2,...] [--remove] [--disable-query-service[=0|false]] <keyspace/shard> <tablet_type>

Options #

  -c, --cells strings           Specifies a comma-separated list of cells to update.
      --denied-tables strings   Specifies a comma-separated list of tables to add to the denylist (for MoveTables). Each table name is either an exact match, or a regular expression of the form '/regexp/'.
      --disable-query-service   Sets the DisableQueryService flag in the specified cells. This flag requires --denied-tables and --remove to be unset; if either is set, this flag is ignored.
  -h, --help                    help for SetShardTabletControl
  -r, --remove                  Removes the specified cells for MoveTables operations.
