Elasticsearch 1.5和Elasticsearch 2.x

Question

I just spent several months building a small search app based on Elasticsearch 1.5 and AngularJS. I know ES 1.5 is old now... but are there major advantages to upgrading to ES 2.0?

Basically what I'm asking is it worth my time to update from ES 1.5 to ES 2.x? If so, how hard is it?

Answer 1

There are a lot of improvements and new features in Elasticsearch 2.X. It is not possible to say which of them will benefit your application, without knowing it better. Checkout this post Elasticsearch 2.0.0 GA released

There are a lot of breaking changes from version 1.X to 2.X. How hard it is to upgrade very much depends on which features you are using and the amount of Elasticsearch specific code you have - take a look at this post: Key points to be aware of when upgrading from Elasticsearch 1.x to 2.x
