Listening on root node does not work in registerDataChangeListener

Bug Resolved Won't Do Unassigned Jakub Morvay Fri, 21 Aug 2015 11:04:30 +0000 Thu, 19 Oct 2017 21:26:51 +0000 Thu, 24 Aug 2017 13:16:31 +0000 Beryllium clustering 0 3 <p>Jakub what is the use case for this?</p> <p>The use case for this BUG-1045, which needs to collect all changes happening in the data store. This works just fine with IMDS, but the CDS implementation fails here, simply because it cannot determine the single shard for the listener.</p> <p>The implementation should instantiate listeners for each shard in existence and combine the results to provide a seamless experience.</p> <p><a href="https://git.opendaylight.org/gerrit/41887" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/41887</a></p> <p>The fix merged does not completely solve the problem, as it does not work across shards (e.g. it does not report data in shards outside of the default shard).</p> <p>This issue will not be fixed for DataChangeListeners, since they are deprecated. Underlying issue is addressed in the MD-SAL's Consumer APIs, which properly assemble changes from a shard hierarchy, supporting listening on root (as it no longer is special).</p> Blocks NETCONF-33 Development External issue ID 4167 External issue URL Issue Type Rank 0|i02qe7:
