Why not use rivers in production?


(Warner Onstine) #1

Getting reintroduced to ES and a co-worker recommended I listen to the
webinar intro that Drew Raines gave as he mentioned something specific
about rivers.

Listening through it I heard him say that they (assuming ES) don't
recommend using rivers in production because it's tied to one node.

Having looked through a lot of the documentation on rivers I do see that
you can specify which rivers run on which nodes so I wasn't sure what the
exact implication was of this statement.

Drew? Or anyone else care to comment?

We're getting ready to push all of our data from MongoDB into ES so that we
can search it and use Kibana for analysis so any insight into this would be
great, thank you :).

A river instance is a singleton in the cluster.
It means that a river is working only on a single node.

It could be reallocated on another node when the first node fails.

I think that's what Drew meant. Basically, rivers does not scale.

My 2 cents
