is possible (or good idea) transition from postgresql to elastic for my website, which is running with php 5.6? Or Is there a way to have postgres database and use elastic only for searching products in my shop (faster?)? How is it work? I mean actualization of data in json elastic database.
Basically, I'd recommend modifying the application layer if possible and send data to elasticsearch in the same "transaction" as you are sending your data to the database.
