Bharat Viswanadham updated HDDS-3623:
-------------------------------------
Status: Patch Available (was: Open)
> Implement getReadCopy in Table.
> -------------------------------
>
> Key: HDDS-3623
> URL: https://issues.apache.org/jira/browse/HDDS-3623
> Project: Hadoop Distributed Data Store
> Issue Type: New Feature
> Reporter: Bharat Viswanadham
> Assignee: Bharat Viswanadham
> Priority: Major
> Labels: pull-request-available
>
> Introduce a getReadCopy in table method.
> As right now, get when a value exists in the cache it returns the cloned
> copy, so that when it used during double-buffer flush, if other threads
> modify the object during the flush time we will see some exceptions like
> https://issues.apache.org/jira/browse/HDDS-2344. To avoid this, all the get()
> values returned are cloned copy if it exists in cache.
> But for few of the requests like OMBucketCreateRequest, we need Volume info
> (OmVolumeArgs, but we don't use this info during double buffer flush, so we
> can safely get a cached copy without doing a clone.
