Adrian Nistor commented on ISPN-7990:
-------------------------------------

I agree with [~gustavonalle], QueryKnownClasses should give you all the types used in this Cache. Knowing the precise type of the value mapped to key K is still not possible, but at least we have narrowed it down to a short list and instead of deleting from all indexes we'll need to delete just from some.

And the good news is by Infinispan 9.2 QueryKnownClasses will also become immutable (declared upfront).

ATM QueryKnownClasses still allows a deprecated autodetection mode (besides declaration in config). There were some technical difficulties in server that we are closed to solving now, and the autodetection can be finally removed in ispn 9.2 and QueryKnownClasses will become a fully immutable list, declared upfront in config, making things much simpler.

> This may be needed in some non frequent scenarios (happening during topology changes) where a write command cannot obtain the previous value to remove it from the index.
