So, I was looking to clean up the database a bit, so I figured I’d see what
was taking up the most space. The import_{something} series of tables looked
like promising clean up candidates. After all, who doesn’t want to free up 750MB
or more when running in a 40GB VM?
QUESTION: Would there be any problems if I deleted records
associated with import_batch_id’s prior to a given date in these related
import_{something} tables?
Grace, Peace, Mercy, and Love,
