Thomas Mueller commented on OAK-2549:
-------------------------------------
I changed the title to "support" instead of "use" append-only mode.
The reason is, first I thought that append only-mode is really needed to avoid
errors, but now I found out that the errors were caused by Thread.interrupt(),
which is now solved thanks to OAK-2571.
> Persistent Cache: support append-only mode
> ------------------------------------------
>
> Key: OAK-2549
> URL: https://issues.apache.org/jira/browse/OAK-2549
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: core
> Reporter: Thomas Mueller
> Assignee: Thomas Mueller
> Fix For: 1.2, 1.1.8, 1.0.13
>
>
> The persistent cache mainly adds data (in some rare cases it overwrites
> existing entries: the list of child nodes, if more child nodes are read).
> Because of that, the storage backend (H2 MVStore currently) can operate in
> append-only mode.
> This should also avoid the following problem: "IllegalStateException: Chunk
> ... no longer exists [1.4.185/9]". This is probably a bug in H2, where old
> chunks are removed too early. This error is not (yet) reproducible, but
> happened while testing.
