We wanted to have blue green deployment in prod environment. ideally we wanted to have 2 rules schema one Blue and one Green and then one data schema. when we want to push the code to prod we wanted it to push it to one of the rules schema (say blue) and have the users slowly migrate to the environment if we don't see any issues. but when i see the pega tables in data schema, i see sharing the below tables with 2 rules schema will be a problem.
PR4_LOG_RULE_USAGE - collecting stats when shutting down and starting
PEGADS.PR_SYS_UPDATESCACHE - rule cache.
will there be any problem if we have 2 rules schema and share the data schema. have anyone tried the blue/green deployment
