Simon Willnauer 5a0b6d1977 Use the primary_term field to identify parent documents (#27469) ... This change stops indexing the `_primary_term` field for nested documents to allow fast retrieval of parent documents. Today we create a docvalues field for children to ensure we have a dense datastructure on disk. Yet, since we only use the primary term to tie-break on when we see the same seqID on indexing having a dense datastructure is less important. We can use this now to improve the nested docs performance and it's memory footprint. Relates to #24362		2017-11-21 15:14:03 +01:00
