Instance Attribute Details

#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 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”

Returns:

• (String) —

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

#cdc_stop_position ⇒ String

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 “

Returns:

• (String) —

  Indicates when you want a change data capture (CDC) operation to stop.

#last_failure_message ⇒ String

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

Returns:

• (String) —

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

#migration_type ⇒ String

The type of migration.

Possible values:

• full-load
• cdc
• full-load-and-cdc

Returns:

• (String) —

  The type of migration.

#recovery_checkpoint ⇒ String

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.

Returns:

• (String) —

  Indicates the last checkpoint that occurred during a change data capture (CDC) operation.

#replication_instance_arn ⇒ String

The ARN of the replication instance.

Returns:

• (String) —

  The ARN of the replication instance.

#replication_task_arn ⇒ String

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

Returns:

• (String) —

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

#replication_task_creation_date ⇒ Time

The date the replication task was created.

Returns:

• (Time) —

  The date the replication task was created.

#replication_task_identifier ⇒ String

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.

Returns:

• (String) —

  The user-assigned replication task identifier or name.

#replication_task_settings ⇒ String

The settings for the replication task.

Returns:

• (String) —

  The settings for the replication task.

#replication_task_start_date ⇒ Time

The date the replication task is scheduled to start.

Returns:

• (Time) —

  The date the replication task is scheduled to start.

#replication_task_stats ⇒ Types::ReplicationTaskStats

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

Returns:

• (Types::ReplicationTaskStats) —

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

#source_endpoint_arn ⇒ String

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

Returns:

• (String) —

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

#status ⇒ String

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.

  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.

Returns:

• (String) —

  The status of the replication task.

#stop_reason ⇒ String

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

• "STOP_REASON_FULL_LOAD_COMPLETED" – Full-load migration completed.

• "STOP_REASON_CACHED_CHANGES_APPLIED" – Change data capture (CDC) load completed.

• "STOP_REASON_CACHED_CHANGES_NOT_APPLIED" – In a full-load and CDC migration, the full load stopped as specified before starting the CDC migration.

• "STOP_REASON_SERVER_TIME" – The migration stopped at the specified server time.

Returns:

• (String) —

  The reason the replication task was stopped.

#table_mappings ⇒ String

Table mappings specified in the task.

Returns:

• (String) —

  Table mappings specified in the task.

#target_endpoint_arn ⇒ String

The ARN that uniquely identifies the endpoint.

Returns:

• (String) —

  The ARN that uniquely identifies the endpoint.

#target_replication_instance_arn ⇒ String

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.

Returns:

• (String) —

  The ARN of the replication instance to which this task is moved in response to running the [ MoveReplicationTask ][1] operation.

#task_data ⇒ String

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 AWS Database Migration Service User Guide.

Returns:

• (String) —

  Supplemental information that the task requires to migrate the data for certain source and target endpoints.
