Dealing with slow _msearch calls

Elastic Stack Kibana
1

Hi,

Kibana 4.x seems to send requests from Dashboard in a single _msearch call. When one has a lot of data in Elasticsearch this could result in timeouts. How do others deal with this, other than increasing connection timeouts?

Thanks,
Otis

I'm also wondering why Kibana 4 is not sending a few queries at once. Browser allows to use a few HTTP connections to a given host. This means instead of sending one big msearch it would be possible to send a few smaller ones and receive results incrementally (dashboards components loading incrementally). Maybe it is possible to configure Kibana 4 somehow and I'm missing something.

This is something I (sorta) was getting at when I raised this - https://github.com/elastic/kibana/issues/4390

But yeah, it'd be nice if it did this.

Thanks Mark.

I'm going to assume other Kibana users will bring this up with time and then maybe the implementation will be changed.

I have found that the issue is very important for large index(daily e-commerce scene...), and
Whether having any plan for implementing the functionality?

Thanks!

Haaa, I understand why my elasticsearch is down after playing with Kibana ;-(

When I query each widget alone (via Sense), the duration is no more than 7ms, but from Kibana, each widget takes more than 1seconde to load data !!!

Any advices about that ?

Thanks you
