Each action has additional options/parameters that can be used to modify its behavior.
actions are common to both MoveTables and Reshard v2 workflows. Only the create action has different parameters, all other actions have common options and similar semantics. These actions are documented separately.
All workflows are identified by targetKeyspace.workflow where targetKeyspace is the name of the keyspace to which the tables are being moved. workflow is a name you assign to the Reshard workflow to identify it.
