It provides the processing power, memory, and network capacity needed to perform schema conversion, data migration, and ongoing replication with minimal downtime. ``` aws.dms_replication ``` ## Fields | Title | ID | Type | Data Type | Description | | -------------------------------- | ---- | ------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | ----------- | | _key | core | string | | account_id | core | string | | cdc_start_position | core | string | 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. | | cdc_start_time | core | timestamp | 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. | | cdc_stop_position | core | string | Indicates when you want a change data capture (CDC) operation to stop. The value can be either server time or commit time. | | failure_messages | core | array | Error and other information about why a serverless replication failed. | | premigration_assessment_statuses | core | json | The status output of premigration assessment in describe-replications. | | provision_data | core | json | Information about provisioning resources for an DMS serverless replication. | | recovery_checkpoint | core | 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. | | replication_config_arn | core | string | The Amazon Resource Name for the ReplicationConfig associated with the replication. | | replication_config_identifier | core | string | The identifier for the ReplicationConfig associated with the replication. | | replication_create_time | core | timestamp | The time the serverless replication was created. | | replication_deprovision_time | core | timestamp | The timestamp when DMS will deprovision the replication. | | replication_last_stop_time | core | timestamp | The timestamp when replication was last stopped. | | replication_stats | core | json | This object provides a collection of statistics about a serverless replication. | | replication_type | core | string | The type of the serverless replication. | | replication_update_time | core | timestamp | The time the serverless replication was updated. | | source_endpoint_arn | core | string | The Amazon Resource Name for an existing Endpoint the serverless replication uses for its data source. | | start_replication_type | core | string | The type of replication to start. | | status | core | string | The current status of the serverless replication. | | stop_reason | core | string | The reason the replication task was stopped. This response parameter can return one of the following values: "Stop Reason NORMAL" "Stop Reason RECOVERABLE_ERROR" "Stop Reason FATAL_ERROR" "Stop Reason FULL_LOAD_ONLY_FINISHED" "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" | | tags | core | hstore_csv | | target_endpoint_arn | core | string | The Amazon Resource Name for an existing Endpoint the serverless replication uses for its data target. |
