------------------------------------
Resolution: Won't Fix
We decided to fix this in a different way. See IMPALA-5990

> Issue Type: Improvement
> Components: Catalog
> Reporter: bharath v
> Assignee: bharath v
>
> When {{compact_catalog_topic=true}}, we need to compact the output of
> getAllCatalogObjects() since it can potentially be quite big (on large
> clusters) and we have the risk of running into JVM array limitations if we
> use the regular TBinaryProtocol.Currently we only compact the output between
> backend < - > statestore, but it makes sense to do it between backend< -
> >frontend in the JNI too.
> Additionally, figure out ways to use native allocations to workaround JVM
> array size limitations during thrift serialization.
