How many vectors do you have in your index to reach up to 2-3 minute delay? Even with a brand new index, after upserting I have to wait 3-5 seconds before the query shows the data.
This is already very bad from an automation perspective where my tests are then verifying or using the data. I either have to retry or sleep – neither of which is desirable. How are people handling this? This needs to be addressed. After upsert and return from the API, the data needs to be available.
