Data Manager Library: Set database table life-span priority #414

Author Name: Duane Costa (Duane Costa) Original Redmine Issue: 2674, https://projects.ecoinformatics.org/ecoinfo/issues/2674 Original Date: 2006-11-21 Original Assignee: Duane Costa

Provide an API for the Calling Application to set a database table life-span priority on specific database tables.

When the upper limit on the database size is reached (see Bug #2673), the Data Manager Library will free up space by reducing the number of cached data tables in the database based on a "least used" removal algorithm. However, the Calling Application should be able to protect specific tables from removal by setting them as high priority. This is a boolean setting, either a table is protected from removal or it isn't.

This task supports Use Case #6 in the Data Manager Library UML documentation.
