feature: add LZ4 compressor #2510

diguage · 2020-04-04T14:51:58Z

LZ4 is an extremely fast Compression algorithm. Maybe it should be supported.

There is an error. And there is no report. So I cannot find it.

Please help me.

I saw the seata/compressor/seata-compressor-lz4/target/checkstyle-result.xml file. There is a tip.

<file name="/Users/diguage/develop/java/javaprojects/seata/compressor/seata-compressor-lz4/src/main/java/io/seata/compressor/lz4/Lz4Util.java">

You don't need to initialize such a large value, just keep the default value

The default size is 32. Is it too small?
Maybe I can change the ARRAY_SIZE to 1024. Is it OK?
