16 16 Connecting with our app Architecture

17 using a ETL WEB APP DATABASE ELASTICSEARCH REST / JSON SQL JDBC HTTP / REST ETL 17

18 think document! Change your mindset: Forget SQL! Index what you want to find A document A JSON object Core field types (string, numbers, booleans) Complex field types (arrays, objects) Additional field types (geo points, geo shapes) 18 18

19 19 Do It Yourself Direct Connection

20 direct connection WEB APP DATABASE SQL JDBC ES-CLIENT HTTP / REST ELASTICSEARCH REST / JSON 20

21 JSON document design PUT /person/person/1 { "name":"joe Pink", "dateofbirth":" ", "address_id":"2", "marketing_id":"3" } PUT /person/address/2 { "city":"paris", "country":"france" } PUT /person/marketing/3 { "cars":1000, "food":1500 } 21
