Hi, I know the latest documentation for CachingRelMetadataProvider shows it has been deprecated. I'm hoping someone here can help me with some history on this class. I'm currently working on a project that is on an older version of Calcite (1.25) and I'm trying to understand the purpose of this class to see if I can safely remove it.
I've looked at the code within the JaninoRelMetadataProvider and I see that there already is caching in there to prevent some code generation. Was there a different level of caching that this was intended for? Or is this the reason why it has been deprecated? Thanks in advance! Steve
