Deleting data doesn't reduce the cost in serverless instance

Working with Data
#1

So the amount of data grows, and the cost per query grows as well, since the index increases…
The problem I’m facing is that even when I deleted 90% of the data, the total read units I’m been billed stayed the same…

The index size didn’t decrease, so that might be the reason, however, I don see a way how to decrease it… (the main problem is with _id index, which I can’t even drop and recreate)

I’m running a serverless instance, and a compact comment doesn’t seem to be available there:
‘CMD_NOT_ALLOWED: compact’,

What to do?

Hi @Juraj_Bezdek,

The problem I’m facing is that even when I deleted 90% of the data, the total read units I’m been billed stayed the same…

Please contact the Atlas support team via the in-app chat regarding this issue as they would have insight into the particular cluster / project. Please provide them details including when the delete was performed (including the date & time + timezone).

Regards,
Jason
