ReplicationTask

Provides information that describes a replication task created by the CreateReplicationTask operation.

CdcStartPosition

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

Type: String

Required: No

CdcStopPosition

Indicates when you want a change data capture (CDC) operation to stop. The value can be either server time or commit time.

Server time example: --cdc-stop-position “server_time:2018-02-09T12:12:12”

Commit time example: --cdc-stop-position “commit_time:2018-02-09T12:12:12“

Type: String

Required: No

LastFailureMessage

The last error (failure) message generated for the replication task.

Type: String

Required: No

MigrationType

The type of migration.

Type: String

Valid Values: full-load | cdc | full-load-and-cdc

Required: No

RecoveryCheckpoint

Indicates the last checkpoint that occurred during a change data capture (CDC) operation. You can provide this value to the CdcStartPosition parameter to start a CDC operation that begins at that checkpoint.

Type: String

Required: No

ReplicationInstanceArn

The ARN of the replication instance.

Type: String

Required: No

ReplicationTaskArn

The Amazon Resource Name (ARN) of the replication task.

Type: String

Required: No

ReplicationTaskCreationDate

The date the replication task was created.

Type: Timestamp

Required: No

ReplicationTaskIdentifier

The user-assigned replication task identifier or name.

Constraints:

Must contain 1-255 alphanumeric characters or hyphens.
First character must be a letter.
Cannot end with a hyphen or contain two consecutive hyphens.

Type: String

Required: No

ReplicationTaskSettings

The settings for the replication task.

Type: String

Required: No

ReplicationTaskStartDate

The date the replication task is scheduled to start.

Type: Timestamp

Required: No

ReplicationTaskStats

The statistics for the task, including elapsed time, tables loaded, and table errors.

Type: ReplicationTaskStats object

Required: No

SourceEndpointArn

The Amazon Resource Name (ARN) that uniquely identifies the endpoint.

Type: String

Required: No

Status

The status of the replication task. This response parameter can return one of the following values:

"moving" – The task is being moved in response to running the MoveReplicationTask operation.
"creating" – The task is being created in response to running the CreateReplicationTask operation.
"deleting" – The task is being deleted in response to running the DeleteReplicationTask operation.
"failed" – The task failed to successfully complete the database migration in response to running the StartReplicationTask operation.
"failed-move" – The task failed to move in response to running the MoveReplicationTask operation.
"modifying" – The task definition is being modified in response to running the ModifyReplicationTask operation.
"ready" – The task is in a ready state where it can respond to other task operations, such as StartReplicationTask or DeleteReplicationTask.
"running" – The task is performing a database migration in response to running the StartReplicationTask operation.
"starting" – The task is preparing to perform a database migration in response to running the StartReplicationTask operation.
"stopped" – The task has stopped in response to running the StopReplicationTask operation.
"stopping" – The task is preparing to stop in response to running the StopReplicationTask operation.
"testing" – The database migration specified for this task is being tested in response to running either the StartReplicationTaskAssessmentRun or the StartReplicationTaskAssessment operation.

Note
StartReplicationTaskAssessmentRun is an improved premigration task assessment operation. The StartReplicationTaskAssessment operation assesses data type compatibility only between the source and target database of a given migration task. In contrast, StartReplicationTaskAssessmentRun enables you to specify a variety of premigration task assessments in addition to data type compatibility. These assessments include ones for the validity of primary key definitions and likely issues with database migration performance, among others.

Type: String

Required: No

StopReason

The reason the replication task was stopped. This response parameter can return one of the following values:

"Stop Reason NORMAL" – The task completed successfully with no additional information returned.
"Stop Reason RECOVERABLE_ERROR"
"Stop Reason FATAL_ERROR"
"Stop Reason FULL_LOAD_ONLY_FINISHED" – The task completed the full load phase. DMS applied cached changes if you set StopTaskCachedChangesApplied to true.
"Stop Reason STOPPED_AFTER_FULL_LOAD" – Full load completed, with cached changes not applied
"Stop Reason STOPPED_AFTER_CACHED_EVENTS" – Full load completed, with cached changes applied
"Stop Reason EXPRESS_LICENSE_LIMITS_REACHED"
"Stop Reason STOPPED_AFTER_DDL_APPLY" – User-defined stop task after DDL applied
"Stop Reason STOPPED_DUE_TO_LOW_MEMORY"
"Stop Reason STOPPED_DUE_TO_LOW_DISK"
"Stop Reason STOPPED_AT_SERVER_TIME" – User-defined server time for stopping task
"Stop Reason STOPPED_AT_COMMIT_TIME" – User-defined commit time for stopping task
"Stop Reason RECONFIGURATION_RESTART"
"Stop Reason RECYCLE_TASK"

Type: String

Required: No

TableMappings

Table mappings specified in the task.

Type: String

Required: No

TargetEndpointArn

The ARN that uniquely identifies the endpoint.

Type: String

Required: No

TargetReplicationInstanceArn

The ARN of the replication instance to which this task is moved in response to running the MoveReplicationTask operation. Otherwise, this response parameter isn't a member of the ReplicationTask object.

Type: String

Required: No

TaskData

Supplemental information that the task requires to migrate the data for certain source and target endpoints. For more information, see Specifying Supplemental Data for Task Settings in the Amazon Database Migration Service User Guide.

Type: String

Required: No
