-----------------------------------
Assignee: Julian Reschke
> RDBDocumentStore: improve logic that decides whether to try string appends
> --------------------------------------------------------------------------
>
> Key: OAK-5622
> URL: https://issues.apache.org/jira/browse/OAK-5622
> Project: Jackrabbit Oak
> Issue Type: Technical task
> Components: documentmk
> Reporter: Julian Reschke
> Assignee: Julian Reschke
> Attachments: OAK-5622.diff
>
>
> While looking at log output for OAK-5387, it became clear that in at least
> that particular test, we are trying updates that we could know in advance to
> fail.
> This is because in this test, all nodes get the same batched appendig
> updates, thus their DATA column will exceed the maximum length for all nodes
> at the same time.
> The correctly working per-document retry logic however immediately tries
> again an append, which consequently fails, and only then tries a full rewrite.
> We could avoid this by leveraging DSIZE from the DB, currently there only for
> debug purposed. We would always fetch it, put it into RDBRow, expose it in
> {{Document}} and then make use of in in the decision logic.
