Hello, I am running an in-memory db and am using the functionality where we override all the OS calls such that we implement our own memory management and file IO. Therefore, I am able to easily track the amount of memory Sqlite is taking up. I have noticed that when I call CREATE INDEX and then the corresponding DROP INDEX, I do not see the memory drop to the same level as it was before the CREATE INDEX. I also call VACUUM after DROP INDEX, which makes no difference.
Is this expected, or does it sound like a bug in Sqlite? Thanks, Dave
