Would it be possible to force a given historical to serve only data from a certain datasource?

Hi,

I wonder if historicals could be configured somehow to serve only data from a certain datasource.

In my case I have a cluster with 3 historical nodes and 2 datasources, A and B. Could node 2 be forced to serve only data from datasource A?

Thanks,

Hi Jorge,

Yes, this is possible. Please set up the historicals into 2 different tiers and then use the retention policy in each datasource to send it to the right tier.

Thanks a lot, Vijeth. I’ve been using the default tier and the default retention policy, so I’ll definitely give what you said a try!
