Hello,
I posted a couple questions here and still considering about applying platinum license for anomaly detection feature.
_10 elasticsearch nodes_ will have the license and they will be used only for "anomaly detection" + "automated reporting" features.
I am planning to configure...
> _All 10 nodes as Data nodes, some of them set as ML nodes, and 3 of them will be configured as Master eligible nodes_.
> _Coordinating + Ingest nodes will be added additionally_.
Is there best guidance for my case about # of ingest nodes? How many ingest / ML nodes are good for set in case they need to work with 10 data nodes?
they can be set as multiple roles configuration. right? (e.g. node works as master/data/ml)
Please advise.
Thank you!

This blog ([https://www.elastic.co/blog/sizing-machine-learning-with-elasticsearch](https://www.elastic.co/blog/sizing-machine-learning-with-elasticsearch)) has good information on best practices with sizing ML nodes with respect to the cluster size.
