Hi Karan,

I'm running into an issue when I run pegasus-monitord in replay mode on some post-processing workflows. It looks like it's trying to add all of my output files to a database, but they've been added already:

  k')

The issue is that it does this for all ~28k files for each workflow, and as a result takes forever. Is there a way to disable this, since it seems like the files have been inserted already? Is it necessary for getting statistics, which is what I'm interested in? Thanks!
