MINOR: Optimise performance of `Topic.validate()`
I included a JMH benchmark and the results follow. The implementation in this PR takes no more than 1/10th of the time when compared to trunk. I also included results for an alternative implementation that is a little slower than the one in the PR. Trunk: ```text TopicBenchmark.testValidate topic avgt 15 134.107 ± 3.956 ns/op TopicBenchmark.testValidate longer-topic-name avgt 15 316.241 ± 13.379 ns/op TopicBenchmark.testValidate very-long-topic-name_with_more_text avgt 15 636.026 ± 30.272 ns/op ``` Implementation in the PR: ```text TopicBenchmark.testValidate topic avgt 15 13.153 ± 0.383 ns/op TopicBenchmark.testValidate longer-topic-name avgt 15 26.139 ± 0.896 ns/op TopicBenchmark.testValidate very-long-topic-name.with_more_text avgt 15 44.829 ± 1.390 ns/op ``` Alternative implementation where boolean validChar = Character.isLetterOrDigit(c) || c == '.' || c == '_' || c == '-'; ```text TopicBenchmark.testValidate topic avgt 15 18.883 ± 1.044 ns/op TopicBenchmark.testValidate longer-topic-name avgt 15 36.696 ± 1.220 ns/op TopicBenchmark.testValidate very-long-topic-name_with_more_text avgt 15 65.956 ± 0.669 ns/op ``` Author: Ismael Juma <ismael@juma.me.uk> Reviewers: Guozhang Wang <wangguoz@gmail.com> Closes #3234 from ijuma/optimise-topic-is-valid |

MINOR: Remove redundant volatile write in RecordHeaders
The JMH benchmark included shows that the redundant volatile write causes the constructor of `ProducerRecord` to take more than 50% longer: ProducerRecordBenchmark.constructorBenchmark avgt 15 24.136 ± 1.458 ns/op (before) ProducerRecordBenchmark.constructorBenchmark avgt 15 14.904 ± 0.231 ns/op (after) Author: Ismael Juma <ismael@juma.me.uk> Reviewers: Jason Gustafson <jason@confluent.io> Closes #3233 from ijuma/remove-volatile-write-in-records-header-constructor |

KAFKA-5150; Reduce LZ4 decompression overhead
- 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. Full benchmark results can be found here https://gist.github.com/xvrl/05132e0643513df4adf842288be86efd Author: Xavier Léauté <xavier@confluent.io> Author: Ismael Juma <ismael@juma.me.uk> Reviewers: Jason Gustafson <jason@confluent.io>, Ismael Juma <ismael@juma.me.uk> Closes #2967 from xvrl/kafka-5150 |
