> [~sergey.soldatov] made a good find through some careful log reading.
> In ProtobufTranslationImpl, some TRACE logging that I had added in
> CALCITE-1159 is causing a bunch of garbage to be created on the heap.
> The trace logging messages should be wrapped in a conditionals to avoid the
> generation of the message itself. I was a little too overzealous thinking
> that the slf4j api was saving me.
