There are a few improvements in 2.12 and 2.13. I am particularly interested in the performance improvements:
* 2.12: "This release brings support for compile only dependencies, improved build script compilation speed and even better IDE support."
* 2.13: "We've achieved performance improvements during Gradle's configuration and execution phase, where we have measured up to 25% improvements to build time in our performance tests. No changes to your build script are necessary to start taking advantage of these improvements."

Kafka Streams seems to hold file handles on the `.lock` files for the state dirs, resulting in an explosion of filehandles over time. Running `lsof` shows the number of open filehandles on the `.lock` file increasing rapidly over time. In a separate test project, I reproduced the issue and determined that in order for the filehandle to be relinquished the `FileChannel` instance must be properly closed. Applying this patch seems to resolve the issue in my job.

This exception is occurring when producer is trying to append a record to a Re-enqueued record batch in the accumulator. We should not allow to add a record to Re-enqueued record batch. This is due a bug in MemoryRecords.java/hasRoomFor() method. After calling MemoryRecords.close() method, hasRoomFor() method should return false.

RollingBounceTest is a system test that cannot be run reliably in unit tests and ReplicationTest is a superset of the
functionality: in addition to verifying that bouncing leaders eventually results in a new leader, ReplicationTest also
validates that data continues to be produced and consumed.

* Use a fixed `Random` seed in `EndToEndLatency.scala` for determinism
* Add `compression_type` to and remove `consumer_fetch_max_wait` from `end_to_end_latency.py`. The latter was never used.
* Tweak logging of `end_to_end_latency.py` to be similar to `consumer_performance.py`.
* Add `compression_type` to `benchmark_test.py` methods and add `snappy` to `matrix` annotation
* Use randomly generated bytes from a restricted range for `ProducerPerformance` payload. This is a simple fix for now. It can be improved in the PR for KAFKA-3554.

* slf4j 1.7.21 includes thread-safety fixes: http://www.slf4j.org/news.html
* snappy 1.1.2.4 includes performance improvements requested by Spark, which apply to our usage: https://github.com/xerial/snappy-java/blob/master/Milestone.md
I ran the stream tests several times and they passed every time while 4.2.0 segfaulted every time.
