- reuse decompression buffers in consumer Fetcher - switch lz4 input stream to operate directly on ByteBuffers - avoids performance impact of catching exceptions when reaching the end of legacy record batches - more tests with both compressible / incompressible data, multiple blocks, and various other combinations to increase code coverage - fixes bug that would cause exception instead of invalid block size for invalid incompressible blocks - fixes bug if incompressible flag is set on end frame block size Overall this improves LZ4 decompression performance by up to 40x for small batches. Most improvements are seen for batches of size 1 with messages on the order of ~100B. We see at least 2x improvements for for batch sizes of < 10 messages, containing messages < 10kB This patch also yields 2-4x improvements on v1 small single message batches for other compression types.
