Use Objectify with Vert.x

Question

Is it possible to integrate Objectify in a Vert.x application ?

Let me give you some context. I have a REST API exposed by Vert.x (3.3.0) that interacts with Google Cloud Datastore using gcloud-java library. Everything works fine but I want to use a higher level API to make all that code easier to read and more maintainable.

Objectify setup indicates that

Objectify requires a filter to clean up any thread-local transaction contexts and pending asynchronous operations that remain at the end of a request.

The thing is, I have no web.xml and Objectify seems to need a servlet filter to work.

Answer 1

It is my understanding that Objectify is specifically designed for Google App Engine. It works well within applications that are deployed to GAE. I did not have any luck using it outside of GAE (not even in Compute Engine). Since you mentioned that you are using the gcloud-java library to access the Cloud Datastore, you might want to check out Catatumbo, an Object Mapping and Persistence Framework that is built on top of gcloud-java. Catatumbo is similar to JPA. Catatumbo is an open source project distributed under the Apache v2 license.
