Can any one please let me know what this table is used for? I saw in different point of time Pega inserts some records to pr_sys_ruleset_index table but not sure what is the purpose of using this particular table and at what point of time Pega writes to this table and what details are actually updated?
pr_sys_ruleset_index contains rows for the System-RuleSet-Index class, which support improved performance by providing quick access to ruleset list has codes.
System-RuleSet-Index Class Documentation:
Class that can be used internally for access to relationships between an application's rulesetlisthash and the rulesets (with versions).
Usage: Each instance is an entry for a particular applications ruleset list hash and ruleset combination. A given application with a single rulesetlisthash will have many entries, one per ruleset in the list. Uses table pr_sys_ruleset_index.
Do not alter the mapping, schema, or structure of these tables except as advised by Pegasystems support staff.
