[jira] [Commented] (LOG4J2-1075) Support bzip2 compression format
for rollover
[ https://issues.apache.org/jira/browse/LOG4J2-1075?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14616853#comment-14616853 ]

--------------------------------------
I hope you are talking about depending on commons compress since there are other formats we'd get for free.

> Project: Log4j 2
> Issue Type: Improvement
> Components: Appenders
> Affects Versions: 2.3

> Fix For: 2.4

> RollingFileAppender and RollingRandomAccessFileAppender currently support two compression formats: gzip and zip. Java has built-in support for these formats so these are guaranteed to work without external dependencies.
> However, there are formats that give much better compression, for example bzip2 results in 40% smaller files.
> At work, we have a requirement to store large log files in smaller format for long term storage. I would like to be able to do this at rollover. Currently we gzip at rollover and have a separate script unzip and bzip2 these files. It would be convenient to be able to use bzip2 directly from log4j at rollover.
> We can leverage the work done here: https://commons.apache.org/proper/commons-compress/
