[ http://jira.qos.ch/browse/LBCORE-128?page=com.atlassian.jira.plugin.system.i... ] Joern Huxhorn commented on LBCORE-128: -------------------------------------- Average event size for protobuf in my testcase is: 2.54kb uncompressed 705b compressed using gzip These are events containing full callstacks, that's why they compress quite good anyway. For real applications, the average event size is 758b (averaged over 19.267.00 events). FYI, we leave the callstack on - even in case of our production system - and the performance penalty is absolutely acceptable. It pays of as soon as something strange happens ;)
Please support implementation of binary log files in RollingFileAppender/FileAppender -------------------------------------------------------------------------------------
Key: LBCORE-128 URL: http://jira.qos.ch/browse/LBCORE-128 Project: logback-core Issue Type: Improvement Components: Appender Affects Versions: 0.9.17 Reporter: Joern Huxhorn Assignee: Ceki Gulcu
This was discussed briefly at http://marc.info/?l=logback-dev&m=124905434331308&w=2 and I forgot to file a ticket about this. Currently, RandomFileAppender => FileAppender => WriterAppender is using the following method in WriterAppender to actually write the data: protected void writerWrite(String s, boolean flush) throws IOException Please add an additional method like protected void writerWrite(byte[] bytes, boolean flush) throws IOException to write to the underlying stream directly. writerWrite(String, boolean) could call that method after performing the transformation internally, making this change transparent for the rest of the implementation. Using a binary format for logfiles could have tremendous performance impact as can be seen here: http://sourceforge.net/apps/trac/lilith/wiki/SerializationPerformance
