大叔经验分享(137)kafka开启压缩
作者:互联网
kafka开启压缩后,可以极大的优化磁盘占用和网络传输开销,开启压缩的参数为compression.type
Specify the final compression type for a given topic. This configuration accepts the standard compression codecs ('gzip', 'snappy', 'lz4', 'zstd'). It additionally accepts 'uncompressed' which is equivalent to no compression; and 'producer' which means retain the original compression codec set by the producer.
这个参数在broker和producer都可以设置,建议:
- 在producer设置,然后broker设置为producer;
- 在producer不设置,统一在broker设置;
ps: 如果两个地方都设置,可能发生两个压缩算法不一致的情况,这样broker在收到消息后需要先解压,再压缩后落盘,增加cpu开销。
开启压缩后可以通过如下命令确认:
bin/kafka-run-class.sh kafka.tools.DumpLogSegments --files /data/kafka/test-0/00000000000000000000.log --print-data-log | grep compresscodec
各种压缩算法的对比如下:
