REPLICATION_USAGE_HISTORY¶

This table function can be used to query the replication history for a specified database within a specified date range. The information returned by the function includes the database name, credits consumed and bytes transferred for replication.

Note

This function returns replication usage activity within the last 14 days.

Syntax¶

REPLICATION_USAGE_HISTORY(
  [ DATE_RANGE_START => <constant_expr> ]
  [ , DATE_RANGE_END => <constant_expr> ]
  [ , DATABASE_NAME => '<string>' ] )
Copy

Arguments¶

All the arguments are optional.

DATE_RANGE_START => constant_expr , . DATE_RANGE_END => constant_expr

The date/time range to display the database replication history:

  • If an end date is not specified, then CURRENT_DATE is used as the end of the range.

  • If a start date is not specified, then the range starts 10 minutes prior to the start of DATE_RANGE_END (i.e. the default is to show the previous 10 minutes of history).

For example, if DATE_RANGE_END is CURRENT_DATE, then the default DATE_RANGE_START is 11:50 PM on the previous day.

DATABASE_NAME => 'string'

Database name. If specified, only shows the history for the specified database.

If a name is not specified, then the results include the data for each database replicated within the specified time range.

Output¶

The function returns the following elements in a JSON object:

Column Name

Data Type

TIMESTAMP_LTZ

END_TIME

  • 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 details, see Snowflake Information Schema.

Examples¶

Retrieve the replication history for a 30 minute range for your account:

select *
  from table(information_schema.replication_usage_history(
    date_range_start=>'2019-02-10 12:00:00.000 +0000',
    date_range_end=>'2019-02-10 12:30:00.000 +0000'));
Copy

Retrieve the history for the last 12 hours for your account:

select *
  from table(information_schema.replication_usage_history(
    date_range_start=>dateadd(H, -12, current_timestamp)));
Copy

Retrieve the history for the past week for your account:

select *
  from table(information_schema.replication_usage_history(
    date_range_start=>dateadd(d, -7, current_date),
    date_range_end=>current_date));
Copy

Retrieve the replication history for the past week for a specified database in your account:

select *
  from table(information_schema.replication_usage_history(
    date_range_start=>dateadd(d, -7, current_date),
