Enable bzip compression in benchmark
------------------------------------
Key: LUCENE-1591
URL: https://issues.apache.org/jira/browse/LUCENE-1591
Project: Lucene - Java
Issue Type: Improvement
Components: contrib/benchmark
Reporter: Shai Erera
Fix For: 2.9
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.
