Recurring analytics services maintenance tasks

Edge for Private Cloud v4.19.01

Many Apigee Analytics Services tasks can be performed using standard Postgres utilities. The routine maintenance tasks you would perform on the Analytics database—such as database reorganization using VACUUM, reindexing and log file maintenance—are the same as those you would perform on any PostgreSQL database. Information on routine Postgres maintenance can be found at

Pruning Analytics Data

As the amount of analytics data available within the Apigee repository increases, you may find it desirable to "prune" the data beyond your required retention interval. Run the following command to prune data for a specific organization and environment:

/opt/apigee/apigee-service/bin/apigee-service apigee-postgresql pg-data-purge org_name env_name number_of_days_to_retain

This command interrogates the "childfactables" table in the "analytics" schema to determine which raw data partitions cover the dates for which data pruning is to be performed, then drops those tables. Once the tables are dropped, the entries in "childfactables" related to those partitions are deleted.

Childfactables are daily-partitioned fact data. Every day new partitions are created and data gets ingested into the daily partitioned tables. So at a later point in time, when the old fact data will not be required, you can purge the respective childfactables.
