I want to add a setting to metadata_config.
Can I update metadata_config without rebuilding the index?

Hi dra,
You can apply the PATCH to modify the metadata_config. Warning. Pods will need to restart and rebuild the metadata index so you could experience some availability issues briefly during this time. I recommend doing it off hours and take a collection ahead of time just in case.

Any rough estimate on how long the downtime would be? Of course it varies depending on how many indexes and how many vectors you have and maybe what pod type you use (just guessing), but is there a rough formula of something like X seconds * num_indexes_per_vector * num_vectors we can assume or example benchmarks we can reference?

Also, would be nice if metadata_config could be added to the documentation you linked. I tested (via curl) and it worked, but it’s not listed and none of the client libraries support it.
