We (Search Platform and DPE SRE) have discussed the need for maintaining and applying OpenSearch cluster dynamic settings in a consistent and visible way in T414095 and T415822.

While I closed T415822, thinking that we could do the work with an initContainer immediately after cluster bootstrap, the Search Platform use case detailed in T414095 suggests we need something a bit more robust.

So far I have been unable to find a ready-made solution for this in the OpenSearch ecosystem. Thus, I believe it is appropriate to start discussing a home-grown solution.

I've created this Google doc to flesh out and collaborate on the design.

Creating this ticket as an umbrella task for the design/implementation/deployment.

Update: Per today's Search Platform standup, this task is on hold until we have finished T414217. Once we've learned more about the capabilities of the new upstream OpenSearch charts, we'll come back.
