Alex Parvulescu updated OAK-3052:
---------------------------------
    Attachment: OAK-3052-v2.patch

attaching improved version. 
the issue I'm seeing now is with the OSGi package export versions:
{code}
[ERROR] org.apache.jackrabbit.oak.plugins.segment: Version increase required; 
detected 3.0.0, suggested 4.0.0
{code}
I don't want to bump up to 4.0.0 as this will probably break a lot of existing 
importers. also this version increase will introduce a big issue with 
backporting.

[~mduerig], [~chetanm] any ideas?

> Currently compaction is skipped if the compaction gain estimator determines 
> that less than 10% of space could be reclaimed. Instead of relying on a hard 
> coded value of 10% we should make this configurable.
