> In KIP-182 we refactored all stores to by plain {{Bytes/byte[]}} stores and 
> only have concrete key/value types on outer layers/wrappers of the stores.
> For this reason, the most inner {{RocksDBStore}} cannot provide useful error 
> messages anymore if a put/get/delete operation fails as it only handles plain 
> bytes.
> Therefore, we should enhance exceptions thrown from {{RocksDBStore}} with 
> corresponding information for which key/value the operation failed in the 
> wrapping stores (KeyValueStore, WindowedStored, and SessionStore).
> Cf https://github.com/apache/kafka/pull/4518 that cleans up {{RocksDBStore}} 
> exceptions.
