> From discussion of KAFKA-2367:
> bq. Caching of conversion of schemas. In the JSON implementation we're
> including, we're probably being pretty wasteful right now since every record
> has to translate both the schema and data to JSON. We should definitely be
> doing some caching here. I think an LRU using an IdentityHashMap should be
> fine. However, this does assume that connectors are good about reusing
> schemas (defining them up front, or if they are dynamic they should have
> their own cache of schemas and be able to detect when they can be reused).
