* When the schema defines _root_, and you want to do atomic/partial updates... ** _root_ needn't be stored or have docValues any more ** _nest_path_ field isn't needed for this any more ** Simplified internal logic * Allow (and recommend, eventually insist) that the _root_ field be passed for atomic/partial updates to child docs. ** In the absence of _root_, assume the _route_ param is equivalent to ameliorate back-compat scope. This is a temporary hack; remove in SOLR-15064. ** One of the two is required; you'll get an exception if the assumption is false. THIS IS A BACK-COMPAT CHANGE * Ensure that the update log contains the _root_ field if it's defined in the schema; in some cases it wasn't. It's important for robustness of atomic/partial updates to child docs. Caveat: the buffer replay scenario is not tested with child docs. * Limited the cases when a realtime searcher is re-opened. It was being applied to any update that included child docs but now only some narrow subset: only for atomic/partial updates, and when the update log contains an in-place update for the same nest because it's complicated to resolve those log entries. * Internal improvements to RealTimeGetComponent to aid clarity & robustness & probably performance... ** Use SolrDocumentFetcher.solrDoc(docID, ReturnFields) instead of more manual loading. Will do more with this in another PR. ** Clarify when only root doc IDs are expected. ** Use Resolution enum more, add PARTIAL, remove DOC_WITH_CHILDREN; enhance docs. ** When have ReturnFields, a Set of "onlyTheseFields" becomes redundant. Add a child doc resolution via a transformer when needed. ** Clarified where copy-field targets are removed * NestPathField should default to single valued, instead of inheriting the schema default, which for ancient schemas was multi-valued. * AddUpdateCommand.getLuceneDocument(s) methods are very internal; made package visible and refactored a bit for clarity * DocumentBuilder: when in-place update, skip id and _root_ here, thus also simplifying further logic * NestedShardedAtomicUpdateTest no longer extends AbstractFullDistribZkTestBase because it wasn't really leveraging the "control client" checking, and it added too much complexity to debug failures. |
