#cdc_start_position ⇒ String

Indicates when you want a change data capture (CDC) operation to start. Use either CdcStartPosition or CdcStartTime to specify when you want a CDC operation 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”

<note markdown=“1”> 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 Attributes When Using PostgreSQL as a Source for DMS].

#cdc_start_time ⇒ Time

Indicates the start time for a change data capture (CDC) operation. Use either CdcStartTime or CdcStartPosition to specify when you want a CDC operation to start. Specifying both values results in an error.

end

#start_replication_task_type ⇒ String

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.
