Michael Dürig commented on OAK-4284:
------------------------------------
As discussed offline with [~alex.parvulescu] and [~frm] we could run a cleanup
(brutal) cycle after a unsuccessful compaction. That cleanup cycle would remove
all segments of exactly the generation added by the (unsuccessful) compaction
step. To make this work we could generalise {{TarReader#mark}} to take e.g. a
predicate instead a cutoff generation.

> Key: OAK-4284
> URL: https://issues.apache.org/jira/browse/OAK-4284
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: segment-next
> Reporter: Michael Dürig
> Labels: cleanup, compaction, gc
> Fix For: 1.6
>
>
> As a result of the new cleanup approach introduced with OAK-3348 (brutal) a
> compaction cycle that is not successful (either because of cancellation of
> because of giving up waiting for the lock) leaves garbage behind, which is
> only cleaned up 2 generations later.
> We should look into ways to remove such garbage more pro-actively.
