I am concerned about the safety of running this against heavily used production indexes. Should I expect some kind of impact on the cluster performance while the mappings are updated?
Welcome to our community!
Yes, there is a cost to doing this, so it'll likely impact your cluster traffic.
Hi Mark, thank you for your answer!
Is there a recommended way for doing this while minimizing the performance impact? Maybe applying updates to one index at a time instead of using a wildcard update?
Or it's better to create new indexes with the updated mapping and then perform a reindex?
I'd start by doing a few, and then seeing what sort of impact it has.
Ultimately it'll depend on how many indices are being updated.
ok, thanks I'll give it a try!
