---------------------------------
Bulk close for 1.7.0
> SegmentNodeBuilder getNodeState can trigger eager flush of child node builder
> -----------------------------------------------------------------------------

> Key: OAK-5863
> URL: https://issues.apache.org/jira/browse/OAK-5863
> Project: Jackrabbit Oak
> Issue Type: Bug
> Components: segment-tar
> Reporter: Alex Parvulescu
> Assignee: Alex Parvulescu
> Fix For: 1.7.0, 1.8
>
>
> It seems that calling {{getNodeState}} on a {{SegmentNodeBuilder}} that is
> not root can reset the {{updateCount}} even if the builder is not root, and
> will start eagerly flushing the state to disk once the update limit is
> reached. [0]
> The fix is relatively simple, don't reset the {{updateCount}} to {{0}} if the
> builder is not a root. I'm now trying to determine the impact on write
> throughput and on the size of the repository, as this is not an easy
> situation to reproduce. It needs to have a very large transaction happening,
> and a call to {{getNodeState}} down the tree.
