VDiff create

vtctldclient VDiff create #

Create and run a VDiff to compare the tables involved in a VReplication workflow between the source and target.

vtctldclient VDiff create

Examples #

vtctldclient --server localhost:15999 vdiff --workflow commerce2customer --target-keyspace customer create
vtctldclient --server localhost:15999 vdiff --workflow commerce2customer --target-keyspace customer create b3f59678-5241-11ee-be56-0242ac120002

Options #

      --auto-retry                                Should this vdiff automatically retry and continue in case of recoverable errors. (default true)
      --debug-query                               Adds a mysql query to the report that can be used for further debugging.
      --filtered-replication-wait-time duration   Specifies the maximum time to wait, in seconds, for replication to catch up when syncing tablet streams. (default 30s)
  -h, --help                                      help for create
      --limit int                                 Max rows to stop comparing after. (default 9223372036854775807)
      --max-extra-rows-to-compare int             If there are collation differences between the source and target, you can have rows that are identical but simply returned in a different order from MySQL. We will do a second pass to compare the rows for any actual differences in this case and this flag allows you to control the resources used for this operation. (default 1000)
      --max-report-sample-rows int                Maximum number of row differences to report (0 for all differences). NOTE: when increasing this value it is highly recommended to also specify --only-pks (default 10)
      --only-pks                                  When reporting missing rows, only show primary keys in the report.
      --source-cells strings                      The source cell(s) to compare from; default is any available cell.
      --tables strings                            Only run vdiff for these tables in the workflow.
      --tablet-types strings                      Tablet types to use on the source and target.
      --tablet-types-in-preference-order          When performing source tablet selection, look for candidates in the type order as they are listed in the tablet-types flag. (default true)
      --target-cells strings                      The target cell(s) to compare with; default is any available cell.
      --update-table-stats                        Update the table statistics, using ANALYZE TABLE, on each table involved in the VDiff during initialization. This will ensure that progress estimates are as accurate as possible -- but it does involve locks and can potentially impact query processing on the target keyspace.
      --wait                                      When creating or resuming a vdiff, wait for it to finish before exiting.
      --wait-update-interval duration             When waiting on a vdiff to finish, check and display the current status this often. (default 1m0s)

Options inherited from parent commands #

      --action_timeout duration              timeout to use for the command (default 1h0m0s)
      --andrew-is-testing                    nothing to see here
      --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.
