Does .ml shared and custom falls under system indices

Hi,

I would like to get some help about understanding hidden and system indices. In our company we are using elasticsearch and kibana 8.19.9.

We ended up in dilemma whether the .ml-anomalies-custom and .ml-anomalies-shared are considered system index or just hidden.

We are running some projects and we do have data views based on .ml where we created some custom visuals based on the results from anomaly detection jobs.

In order to verify deprecation warnings, I did few example queries where i queried one system index which i got warning that in future version it’s going to be blocked, while .ml doesn’t have that warning.

My question is, are we gonna be allowed to point to .ml index by simply creating data view in version 9.n? Or this option won’t be possible?

Hello @residual-07

Welcome to the community!!

Could you please share the index name for which you got that deprecation warning.

Yes as per documentation we can see the same message provided :

On 9.x i see we are able to create the data view for .ml* :

Thanks!!
