> > I'm curious, what is the reason why this PR is blocked? > > I was waiting for [CALCITE-4942](https://issues.apache.org/jira/browse/CALCITE-4942) to be resolved since it could potentially substantially reduce the amount of boilerplate and reimplementation in this patch. Note that I did get [ProxyingMetadataHandlerProvider|https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/rel/metadata/ProxyingMetadataHandlerProvider.java] which allows one to use metadata without runtime compilation. It isn't fast but at least it is functional in things like GraalVM. I thought there was not agreement on how to go forward with CALCITE-4942. From what I recall their was disagreement on wether to expose the lambda implementation classes or to use the ProxyingMetadataHandlerProvider to bridge interfaces between the metadata query and the handler generator. -- This is an automated message from the Apache Git Service.
