Hi Joern, Plese enter a bug report with as much information as you can about the code you'd like to see changed. In principle, very little code is involved in actually writing to the file so the task would seem rather easy. However, WriterAppender on which FileAppender and RollingFileAppender are built upon uses a Writer to write whatever it is that needs to be written. Unfortunately, a Writer knows how to writes String or chars, but not bytes. Nevertheless, I think it's feasible with some work... Joern Huxhorn wrote:
Hi Ceki.
I've seen that you are working on the FileAppenders again. Have you seen this mail I wrote? What do you think about it?

Hi Ceki.
I'd like to implement a file appender that writes the binary Lilith format, i.e. gzipped protobuf-serialized events, instead of Strings. I'd also like to have the same functionality that's supported by RollingFileAppender right now.
Unfortunately, there seems to be no way to simply write bytes instead of a String. How would you go from here? Reimplementing everything from the start seems to be a pretty bad idea.
What do you think about enhancing the RFA so it's using byte[] instead of Strings? The current behavior could be implemented using those methods + string.getBytes("UTF-8") or CharsetEncoder...
Any idea, suggestions?
Regards, Joern.
