Right now the creation of the shard is a bit slow.

Hi @fulmicoton and team, thank you for the great work on Quickwit. Are there any ETAs when can we expect to see 0.9? I've been tracking the project, and it looks like the last piece for 0.9 as per Quickwit 0.9. Thank you.

#5679 starts addressing this issue. It is not a silver bullet, you can still expect a bit of throttling because the scaling decisions take 5-10secs to be taken. I don't think any other action on this front before 0.9. We just have to also get a few other fixes out and perform some extra tests and we should be good to go!

There is also #5655 that adds a small indicator in the CLI ingest result.
