Add support for Mongeez

[eddumelendez]

Mongezz is a Document Change Management like Liquibase for RDBMS but for MongoDB.

Any updates on this ?

[philwebb]

@mkhanal It's not on the immediate roadmap for 1.3 I'm afraid.

[eddumelendez]

I am going to work on this.

@olivergierke any experience with Mongeez? @wilkinsona Any concerns about adding this from a platform perspective?

I am not particularly opposed to this but I don't see much advantage over simply having a component that uses MongoOperations to execute what you would write into an XML file in Mongeez. The former even has quite some advantages over the latter:

• Type-checked execution of functionality
• Exception translation
• Support for POJOs (to make sure we create documents that match the application schema and registered custom conversions)

Staying with core Spring Boot means also allows you to use Spring Data repositories for initialization etc. I haven't seen much usage of Mongeez in the wild, probably because most of the Mongo usage we see is on top of Spring Data MongoDB so that this custom solution is sort of obsolete.

I have a couple of concerns from a Platform perspective:

• The last release was in September 2013 and the last commit was in October 2014. That wouldn't be a problem if the project was "finished", but that doesn't appear to be the case. For example, a schema for the XML files is described as work in progress
• It depends on Mongo Java Driver 2.11.x. We'd need to be sure it works with newer 2.x drivers, and also that it'll continue to work with Mongo 3.0 which we'll want to become the default in Boot at some point.

In terms of the functionality, Mongeez allows you to use discrete changesets so you can migrate a database to the latest content from different starting points. That's quite a valuable addition over rolling your own with MongoOperations, imo.

What if added this as request for enhancement for Spring Data MongoDB? It doesn't look like too much code and maybe we can add a more Java-driven variant (maybe even like Flyway but simpler) of the XML flavor? We could get in touch with the authors of Mongeez an see whether they're interested in contributing.

[wilkinsona]

+1 – that sounds like the best of both worlds to me

I've created DATAMONGO-1241 for further reference.

Given the comments above I'm going to close this one and we'll go with DATAMONGO-1241 instead. Thanks for the suggestion @eddumelendez.
