Merge operations still assume full materialization of nodes, which is inefficient from the perspective of the work done and also leads to needless memory overhead in situations where LazyContainerNode could be used.</p> <p>Operating System: All<br/> Platform: All</p> YANGTOOLS-501

DataTree: lazy merge operations

This is not a fair assumption, as previous processing stages do not know against what data tree state the modification will be applied &#8211; hence their only reasonable option is to perform minimal materialization required to maintain the ModifiedNode contract.</p> <p>SchemaAwareApplyOperation then needs to finish instantiation of ModifiedNode tree such that the resulting DataTreeCandidate holds an accurate delta.</p> <p><a href="https://git.opendaylight.org/gerrit/26853" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/26853</a></p> <p>Patch on stable/beryllium: <a href="https://git.opendaylight.org/gerrit/#/c/32752/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/32752/</a></p> Blocks YANGTOOLS-500 Development External issue ID 4295 External issue URL Issue Type ODL SR Target Milestone Rank 0|i027m7:
