 [KIP-770](https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=186878390) deprecates config `cache.max.bytes.buffering` in favor of the newly introduced config `statestore.cache.max.bytes`. To improve monitoring, two new metrics `input-buffer-bytes-total` and `cache-size-bytes-total` were added at the DEBUG level. Note, that the KIP is only partially implemented in the 3.4.0 release, and config `input.buffer.max.bytes` is not available yet.

The `Integer StreamPartitioner.partition()` method is deprecated and replaced by the newly added `Optiona≶Set<Integer>>StreamPartitioner.partitions()` method, which enables returning a set of partitions to send the record to.

 [KIP-862](https://cwiki.apache.org/confluence/x/WSf1D) adds a DSL optimization for stream-stream self-joins. The optimization is enabled via a new option `single.store.self.join` which can be set via existing config `topology.optimization`. If enabled, the DSL will use a different join processor implementation that uses a single RocksDB store instead of two, to avoid unnecessary data duplication for the self-join case.
