Shawn Heisey commented on LUCENE-5914:
--------------------------------------
bq. Haven't looked at the patch I confess, but is there a way to turn
compression off completely?
+1.
>From what I understand, this would be relatively straightforward in Lucene,
>where you can swap low-level components in and out pretty easily, but I'm
>really looking for that option to be user-configurable in Solr. I know that
>will require a separate issue. For my index, compression is a good thing, but
>like Erick, I've seen situations with Solr on the list and IRC where it really
>hurts some people.
> More options for stored fields compression

> Since we added codec-level compression in Lucene 4.1 I think I got about the
> same amount of users complaining that compression was too aggressive and that
> compression was too light.
> I think it is due to the fact that we have users that are doing very
> different things with Lucene. For example if you have a small index that fits
> in the filesystem cache (or is close to), then you might never pay for actual
> disk seeks and in such a case the fact that the current stored fields format
> needs to over-decompress data can sensibly slow search down on cheap queries.
> On the other hand, it is more and more common to use Lucene for things like
> log analytics, and in that case you have huge amounts of data for which you
> don't care much about stored fields performance. However it is very
> frustrating to notice that the data that you store takes several times less
> space when you gzip it compared to your index although Lucene claims to
> compress stored fields.
> For that reason, I think it would be nice to have some kind of options that
> would allow to trade speed for compression in the default codec.
