REPLICATION_GROUP_REFRESH_HISTORY view¶

This Account Usage view can be used to query the refresh history for a specified replication or failover group.

See also:: REPLICATION_GROUP_REFRESH_HISTORY, REPLICATION_GROUP_REFRESH_HISTORY_ALL (Information Schema table function)

Columns¶

Column Name	Data Type	Description
REPLICATION_GROUP_NAME	VARCHAR	Name of the secondary replication or failover group.
REPLICATION_GROUP_ID	NUMBER	Internal/system-generated identifier for the replication or failover group.
PHASE_NAME	VARCHAR	Current phase in the replication operation. For the list of phases, see the Usage notes.
START_TIME	TIMESTAMP_LTZ	Time when the replication operation began.
END_TIME	TIMESTAMP_LTZ	Time when the replication operation finished, if applicable. `NULL` if it is in progress.
JOB_UUID	VARCHAR	Query ID for the refresh job.
TOTAL_BYTES	VARIANT	A JSON object that provides detailed information about refreshed databases: `totalBytesToReplicate`: Total number of bytes expected to be replicated. `bytesUploaded`: Actual number of bytes uploaded. `bytesDownloaded`: Actual number of bytes downloaded. `databases`: List of JSON objects containing the following fields for each member database: `name`: Name of the database. `totalBytesToReplicate`: Total bytes expected to be replicated for the database.
OBJECT_COUNT	VARIANT	A JSON object that provides detailed information about refreshed objects: `totalObjects`: Total number of objects in the replication or failover group. `completedObjects`: Total number of objects completed. `objectTypes`: List of JSON objects containing the following fields for each type: `objectType`: Type of object (for example users, roles, grants, warehouses, schemas, tables, columns, etc). `totalObjects`: Total number of objects of this type in the replication or failover group. `completedObjects`: Total number of objects of this type that were completed.
PRIMARY_SNAPSHOT_TIMESTAMP	TIMESTAMP_LTZ	Timestamp when the primary snapshot was created.
ERROR	VARIANT	NULL if the refresh operation is successful. If the refresh operation fails, returns a JSON object that provides detailed information about the error: `errorCode`: Error code of the failure. `errorMessage`: Error message of the failure.

Usage notes¶

Latency for the view may be up to 180 minutes (three hours).

To view real-time refresh progress, use the REPLICATION_GROUP_REFRESH_HISTORY, REPLICATION_GROUP_REFRESH_HISTORY_ALL table function.

Results are only returned for secondary failover or replication groups in the current account (the target account).

The following is the list of phases in the order processed:

#	Phase name	Description
1	`SECONDARY_SYNCHRONIZING_MEMBERSHIP`	The secondary replication or failover group receives information from the primary group about the objects included in the group, and updates its membership metadata.
2	`SECONDARY_UPLOADING_INVENTORY`	The secondary replication or failover group sends an inventory of its objects in the target account to the primary group.
3	`PRIMARY_UPLOADING_METADATA`	The primary replication or failover group creates a snapshot of metadata in the source account and sends it to the secondary group.
4	`PRIMARY_UPLOADING_DATA`	The primary replication or failover group copies the files the secondary group needs to reconcile any deltas between the objects in the source and target accounts.
5	`SECONDARY_DOWNLOADING_METADATA`	The secondary replication or failover group applies the snapshot of the metadata that was sent by the primary. The metadata updates are not applied atomically and instead applied over time.
6	`SECONDARY_DOWNLOADING_DATA`	The secondary replication or failover group copies the files sent by the primary group to the target account.
7	`COMPLETED` / `FAILED` / `CANCELED`	Refresh operation status.

Examples¶

To retrieve the refresh history for the secondary failover group myfg, execute the following statement:

SELECT phase_name, start_time, end_time,
       total_bytes, object_count, error
  FROM SNOWFLAKE.ACCOUNT_USAGE.REPLICATION_GROUP_REFRESH_HISTORY
  WHERE replication_group_name = 'MYFG';

To retrieve the last refresh record for each replication or failover group, execute the following statement:

SELECT replication_group_name, phase_name,
       start_time, end_time,
       total_bytes, object_count, error,
       ROW_NUMBER() OVER (
         PARTITION BY replication_group_name
         ORDER BY end_time DESC
       ) AS row_num
  FROM SNOWFLAKE.ACCOUNT_USAGE.REPLICATION_GROUP_REFRESH_HISTORY
  QUALIFY row_num = 1;
