REPLICATION_USAGE_HISTORY

Supported regions for feature

This feature is not available in the People’s Republic of China.

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.
