LISTING_REFRESH_HISTORY

Returns the past 14 days of refresh history for a cross-cloud auto-fulfillment listing. The information returned contains replication details for refresh events where the listing is synchronized to a specified target region.

This function is available to providers of listings who have any privilege on the specified listing.

Syntax

LISTING_REFRESH_HISTORY(
  LISTING_NAME => '<listing_name>'
  [ , SNOWFLAKE_REGION => '<snowflake_region>' ]
  [ , REGION_GROUP => '<region_group>' ] )
Copy

Arguments

Required

LISTING_NAME => 'listing_name'

SQL identifier of a cross-cloud auto-fulfillment listing in this account. The SQL identifier for listings can be found in the name column returned by show listings in data exchange <exchange_name>. Similarly, the SQL identifier for data exchanges can be found in the name column returned by show data exchanges.

Optional

SNOWFLAKE_REGION => 'snowflake_region'

The Snowflake region group to which the listing is replicated, where you can view the refresh history for that replication. This follows the same formatting as the column snowflake_region returned by SHOW REGIONS. If no region is specified, the history for all target regions is displayed.

REGION_GROUP =>  'region_group'

The Snowflake region group to which the listing is replicated, for which you can view the refresh history.

PUBLIC by default. This argument only needs to be specified if the target region being monitored is in a US government or Virtual Private Snowflake region.

Output

The function returns the following columns:

Column Name

Data Type

Description

LISTING_NAME

TEXT

Name of the cross-cloud auto-fulfillment listing in this account.

SNOWFLAKE_REGION

TEXT

Name of the Snowflake region the listing is replicated to. For example, aws_us_east_1.

REGION_GROUP

TEXT

Name of the Snowflake region group the listing is replicated to. For example, PUBLIC.

PHASE

TEXT

Current phase in the replication operation, represented as one phase out of a total of X phases. For example, 2/6.

PHASE_NAME

TEXT

Name of the replication phases completed (or in progress) so far.

For the list of phases, see usage notes.

PROGRESS

TEXT

The current replication progress as a percentage.

START_TIME

TIMESTAMP_LTZ

Time when the replication phase began.

END_TIME

TIMESTAMP_LTZ

Time when the phase finished, if applicable.

NULL if the phase is in progress or is the terminating phase (COMPLETED/FAILED/CANCELED).

JOB_UUID

TEXT

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

  • Only returns rows for a role with any privilege on the listing.

  • Only returns rows for a listing in the current account.

  • When calling an Information Schema table function, the session must have an INFORMATION_SCHEMA schema in use or the function name must be fully-qualified.

    For more information, see Information Schema.

  • Phase list in the order processed:

    1. SECONDARY_SYNCHRONIZING_MEMBERSHIP

    2. SECONDARY_UPLOADING_INVENTORY

    3. PRIMARY_UPLOADING_METADATA

    4. PRIMARY_UPLOADING_DATA

    5. SECONDARY_DOWNLOADING_METADATA

    6. SECONDARY_DOWNLOADING_DATA

    7. COMPLETED / FAILED / CANCELED

  • The output will also include the history of other listings that reference the same database, as they are refreshed together. If the input is an application listing, it contains the history of all application listings in the given region.

  • In the PRIMARY_UPLOADING_DATA and SECONDARY_DOWNLOADING_DATA phases, the totalBytesToReplicate value is estimated prior to the replication operation. This value may differ from the totalBytesToUpload or totalBytesToDownload value in the respective phase.

    For example, if during the PRIMARY_UPLOADING_DATA phase, a previous replication operation uploaded some bytes but was canceled before the operation completed, those bytes would not be uploaded again. In that case, totalBytesToUpload would be lower than totalBytesToReplicate.

Examples

Retrieve the history for the listing my_listing refreshing to AWS US East-1, a public cloud region.
