Elastic 8.17 and _source

Elastic Stack Elasticsearch

I was reading through 8.17.0 release note. first thing it says _source is no longer available without subscription.

is this means if you create index it won't have _source and this means not able to update, update_by_query and reindex? is my understanding correct?

It's synthetic source, not the _source field itself. So you can still reindex, update by query, etc...

But if you are using explicitly this "mode": "synthetic" in your mapping, then there's a modification. If you are not, there is no change.
