Hi,

Setting up Full Update and accelerator refresh interval to 1 hrs. Does not clean up old acceleraotr directory. Size grows every hour and disk space is exhausted in sometime.

I am using mysql database. How do I cleanup old acceleration files automatically?

HI,

Dremio will periodically clean up old acceleration files, how long have you had Dremio running without seeing disc space being cleaned up?
