Sure --- delete them from the pre-image, then rebuild the CDB
database.

CDB is Constant DataBase, write-once.

The lifecycle of a .cdb file is, it's created once --- preferably
in a tmp file that's moved into place with atomic rename(2). Then
one or more readers open is to read, and read from it as long as
they want, doing as many queries as they want. If the readers
periodically check, between reads, via re-opening the file or just
stat(2)-ing it to see if it's changed, they can see updates ---
rewrites --- in a timely fashion while avoiding any danger of a
corrupt read from the file being updated mid-read.
