Is JOIN operation possible in ElasticSearch using any ES Connector for presto or Hive (ElasticSearch-Hadoop)? -
as know join operation not possible in elasticsearch among indices, can achieved using presto or hive, i.e. can join operation using elasticsearch connector presto or hive ?
can join in elasticsearch using elasticsearch-hadoop - https://github.com/elastic/elasticsearch-hadoop ?
yes, if write connector elasticsearch presto, can use joins. joins in presto processed inside core engine, , don't involve connector, except read underlying data.
