>> IMO, it will be much better if you describe the task you need to solve
Task is in CORE-6199 but i need only part of it. My current solution is with OAT + RDB$RECORD_VERSION and now i am looking into FB4 changes if it can help more. It is better now because of existence of RDB$GET_TRANSACTION_CN. But it still do not use and index to query. And my question was about optimize this part to use an expression index somehow.
