[hibernate-dev] [HSEARCH] Feedback on Elasticsearch presentation

Hey all, I've done a presentation of the new Elasticsearch integration with a Elasticsearch developer+advocate. Here are some key inputs from the listener feedback. The presentation was a Tools in Action (30 mins) where we took a JPA app, added Elasticsearch for entity indexing manually (describing issues) and then restart with Hibernate Search. There was big interest, so a bit less feature release earlier will help more than "better" later. One big feedback is that we need to help people on the analyzer definition in Elasticsearch (from our metadata): - map existing ES analyzers to ours - offer way to define an analyzer and have it pushed with the index definition when we create them - figure out a way to embed the additional key options like nbr of shards when we create the index definition - offer an export function for our index definition so that people can curl it themselves The other part was about mapping: - support for parent child: parent / child is a bit like Infinispan grouping where the children are colocated in the same node as the parent. So it's a single node join. David was not necessarily recommending me to support that from the get go because we already handle the right denormalization via HSearch. - support for nested mapping and nested queries. This is also a relatively expensive prop so not all nested structure should be mapped as ES nested. Here we probably should offer a specific mapping annotation or option and write the nested query accordingly For the mapping part, we probably should write these down in the FAQ as to why we don't do them right away and the workaround available.
