MoveTables switchtraffic
vtctldclient MoveTables switchtraffic #
Switch traffic for a MoveTables VReplication workflow.
vtctldclient MoveTables switchtraffic
Examples #
vtctldclient --server localhost:15999 MoveTables --workflow commerce2customer --target-keyspace customer switchtraffic --tablet-types "replica,rdonly"
Options #
-c, --cells strings Cells and/or CellAliases to switch traffic in.
--dry-run Print the actions that would be taken and report any known errors that would have occurred.
--enable-reverse-replication Setup replication going back to the original source keyspace to support rolling back the traffic cutover. (default true)
--force Force the traffic switch even if some potentially non-critical actions cannot be performed; for example the tablet refresh fails on some tablets in the keyspace. WARNING: this should be used with extreme caution and only in emergency situations!
-h, --help help for switchtraffic
--initialize-target-sequences When moving tables from an unsharded keyspace to a sharded keyspace, initialize any sequences that are being used on the target when switching writes.
--max-replication-lag-allowed duration Allow traffic to be switched only if VReplication lag is below this. (default 30s)
--shards strings (Optional) Specifies a comma-separated list of shards to operate on.
--tablet-types strings Tablet types to switch traffic for.
--timeout duration Specifies the maximum time to wait, in seconds, for VReplication to catch up on primary tablets. The traffic switch will be cancelled on timeout. (default 30s)
Options inherited from parent commands #
--action_timeout duration timeout to use for the command (default 1h0m0s)
--compact use compact format for otherwise verbose outputs
--format string The format of the output; supported formats are: text,json. (default "text")
--server string server to use for the connection (required)
--target-keyspace string Target keyspace for this workflow.
--topo-global-root string the path of the global topology data in the global topology server (default "/vitess/global")
--topo-global-server-address strings the address of the global topology server(s) (default [localhost:2379])
--topo-implementation string the topology implementation to use (default "etcd2")
-w, --workflow string The workflow you want to perform the command on.
