How to avoid index.store.hybrid.mmap.extensions deprecation warning?

OpenSearch

Versions (relevant - OpenSearch/Dashboard/Server OS/Browser):

OpenSearch: 2.15.0
Dashboard: 2.15.0
Server OS: CentOS 7.8
Browser: Vivaldi 6.5.3206.63/Edge 126.0.2592.68

Describe the issue:

I installed OpenSearch from the 2.15.0 tar ball and I added via the DevTools Console my first record to a new index. :smile:

The record gets added, but in resposne I see a index.store.hybrid.mmap.extensions deprecation comment. (For whole message see below in the Log section).

Where and how do I have to change the index.store.hybrid.mmap.extensions setting to avoid this warning?

Configuration:

OpenSearch Test install with security and security plugin removed.

Relevant Logs or Screenshots:

#! Deprecation: [index.store.hybrid.mmap.extensions] setting was deprecated in OpenSearch and will be removed in a future release!

Hi @halloleo , it seems like some plugins like [1] still use this setting at the moment, you could uninstall these plugins if you don’t need them. Thank you.

Thanks @reta.

Is the k-NN plugin installed by default when I run OpenSearch from the TAR ball?
