Guozhang Wang commented on KAFKA-3740:
--------------------------------------
Since we need to pass the StreamsConfig object to the storage layers anyways,
one approach to do that is to expose the configs via `ProcessorContext`, by
leveraging `AbstractConfig.originalsWithPrefix`. For example, users can specify
configs like "rocksdb.xx.xx" and then with a new API:
Map<String, Object> properties ProcessorContext.configs("prefix");

> Today most of the rocksDB configs are hard written inside {{RocksDBStore}},
> or the default values are directly used. We need to make them configurable
> for advanced users. For example, some default values may not work perfectly
> for some scenarios:

> One way of doing that is to introduce a "RocksDBStoreConfigs" objects similar
> to "StreamsConfig", which defines all related rocksDB options configs, that
> can be passed as key-value pairs to "StreamsConfig".
