I need to refeed the data from application log files. They may or may not
have duplicate rows. The only way I can filter these it to feed them all in
parallel using Perl & DBI into a unique index. That's what takes the time.

Do you suggest I rebuild the entire database or just the affected table? I
have approx 400million rows in the entire database.
