Shai Erera updated LUCENE-1591:
-------------------------------
Attachment: LUCENE-1591.patch
Ok I'm convinced. I moved to commons-compress and it works great. The jar is
smaller and it does add the logical dependency. Since this project is still
young we should expect changes, which is good since it means we can actually
improve the In(Out) compressing streams to use more efficient methods, such as
read(byte[]) and write(byte[]).

> bzip compression can aid the benchmark package by not requiring extracting
> bzip files (such as enwiki) in order to index them. The plan is to add a
> config parameter bzip.compression=true/false and in the relevant tasks either
> decompress the input file or compress the output file using the bzip streams.
> It will add a dependency on ant.jar which contains two classes similar to
> GZIPOutputStream and GZIPInputStream which compress/decompress files using
> the bzip algorithm.
> bzip is known to be superior in its compression performance to the gzip
> algorithm (~20% better compression), although it does the
> compression/decompression a bit slower.
> I wil post a patch which adds this parameter and implement it in
> LineDocMaker, EnwikiDocMaker and WriteLineDoc task. Maybe even add the
> capability to DocMaker or some of the super classes, so it can be inherited
> by all sub-classes.
