使用Restheart的汇总方法

Question

I have a remote database on MongoDB and i want to execute an aggregate method for grouping entries wrt a certain field using restheart. My query looks like this

 db.musa.aggregate([{$group:{_id:"$username"}}])

this query returns a list of unique users in my database but i am not sure how to implement it using restheart. Is it even possible to do so?

Answer 1

I'm from the restheart.org team...

a similar question has been already asked on github https://github.com/SoftInstigate/restheart/issues/55

I'm pasting here the answer:

currently aggregate queries are not supported.

note that this is in the roadmap and planned for next version

jira task 41: https://softinstigate.atlassian.net/browse/RH-41

as a workaround you can implement a custom application handler: documentation at https://softinstigate.atlassian.net/wiki/x/IoCw

Answer 2

RESTHeart release 1.1 is out and now can manage aggregation operations : both aggregation pipelines and map reduce functions are supported.

Aggregations operations process data records and return computed results. Aggregation operations group values from multiple documents together, and can perform a variety of operations on the grouped data to return a single result.
