Disk usage problem after delete mutation

My usage scenario is to store a large amount of data every day, and then find some of the data, about 99%, and execute delete

but after executing the deletion mutation, the disk usage is still increasing.

So what should I do so that the data that needs to be deleted is actually deleted from the disk?

Deletion of data happens during the compaction of LSM tree levels. If you are not writing enough data to trigger a level compaction, the data won’t be deleted on disk. Check out these links for further information:
