Hi guys,

Would it be considered odd to have a stack containing both Mongo and  
ElasticSearch?

We have an application in development that currently uses Mongo as a  
DataStore. We've recently come across ElasticSearch and have started  
working with it as we want to use it to index lots of documents, but the  
more I learn about ElasticSearch, the more I wonder, what is the point of  
having Mongo DB here? I could simply move all the data (which is actually  
not that much) from Mongo into its own index in ElasticSearch and be done  
with Mongo completely.

Or am I missing something?

Regards  
Kash.
