hey folks - I've been materializing an asset locally during testing, and I see it has "-1" for the count of successful partitions. what does this mean?

Hi Rob. This is an error. How did you encounter this error? Did it involve changing a partitions def?

@claire I may have changed the start date on a partition def during testing, but I can't recall. when I get some time I can try to repro exactly how to get to this state

that would be much appreciated 🙏 happy to help out from there and put in a fix to resolve this

@claire yeah so this happened again during a backfill. there were originally 15 failed partitions, then I kicked off a backfill, and it looks like this:

@Rob Sicurelli thanks for looking into this--i'll try and repro this and get a fix out

yes - the numbers are good after the backfill

ah okay, looks like the in progress count might be incorrectly subtracted from the "materialized" count when those in progress partitions have not previously been materialized cc @johann

What version of dagster are you running?

haha I got it, if a partition has ever been materialized and is in progress and the most recent attempt failed, then we double subtract from materialized
