	// The type of replication task to start. When the migration type is full-load or
	// full-load-and-cdc , the only valid value for the first run of the task is
	// start-replication . This option will start the migration. You can also use
	// ReloadTables to reload specific tables that failed during migration instead of
	// restarting the task. The resume-processing option isn't applicable for a
	// full-load task, because you can't resume partially loaded tables during the full
	// load phase. For a full-load-and-cdc task, DMS migrates table data, and then
	// applies data changes that occur on the source. To load all the tables again, and
	// start capturing source changes, use reload-target . Otherwise use
	// resume-processing , to replicate the changes from the last stop position.
	//
	// This member is required.

	// Indicates when you want a change data capture (CDC) operation to start. Use

	// to start. Specifying both values results in an error. The value can be in date,
	// checkpoint, or LSN/SCN format. Date Example: --cdc-start-position
	// “2018-03-08T12:12:12” Checkpoint Example: --cdc-start-position
	// "checkpoint:V1#27#mysql-bin-changelog.157832:1975:-1:2002:677883278264080:mysql-bin-changelog.157832:1876#0#0#*#0#93"
	// LSN Example: --cdc-start-position “mysql-bin-changelog.000024:373” When you use
	// this task setting with a source PostgreSQL database, a logical replication slot
	// should already be created and associated with the source endpoint. You can
	// verify this by setting the slotName extra connection attribute to the name of
	// this logical replication slot. For more information, see Extra Connection
