Michael McCandless commented on LUCENE-1591:
--------------------------------------------
bq. I wonder why does EnwikiDocMaker extend LineDocMaker?
I'm not sure... I agree it'd be cleaner to not subclass LineDocMaker, and
factor out DocState into BasicDocMaker.
bq. Should we first check forever, and only if it's true call openFile()?
Yes, let's fix that!
bq. resetInputs() reads the docs.file property and throws an exception if it's
not set. Shouldn't this code belong to setConfig?
I think it should, but I vaguely remember some odd reason why I put it in
resetInputs... try moving it and see?
> 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.
