Hi everyone, we are struggling with elasticSearch integration. Sql4es has started working on support for ES 5.X, but from our tests it still doesn't cover attributes being list or object types.
I have started an elasticsearch storage plugin for 1.10 but it seems quite difficult to understand Apache Drill interfaces (Java-Docs are not quite useful), if you can point me on some documentation explaining the interfaces to implement it would be nice.
I have reviews some of the MongoDB implementation, and based on it, I started coding (https://github.com/javiercanillas/drill-storage-elastic). It's not finished yet, it is still on development.
Any recommendations on documentation or any advice it will be very welcome.
