06/15/2023, 12:21 AMThe interval seems to be saying year 20150912. What date are you trying to use?

06/15/2023, 8:20 PMHi @Ben Krug
That's the one I am setting the retention to.
Hobie Chhina
06/15/2023, 8:21 PMThis interval - 20150912-01-01T010000.000Z/20150912-01-01T020000.000Z
b
Ben Krug
06/15/2023, 9:54 PMYear 20150912, ie about 20M years in the future?
h
Hobie Chhina
06/15/2023, 9:55 PMIt's actually 2015 09 12
Hobie Chhina
06/15/2023, 9:55 PMYYYY MM DD
b
Ben Krug
06/15/2023, 9:56 PMOh, then maybe you want something like 2015-09-12T010000.000Z-2015-09-12T020000.000Z?
Ben Krug
06/15/2023, 9:57 PMOh wait, do you have segments in that time interval, and you're using the UI to try to drop them, right?
h
Hobie Chhina
06/15/2023, 9:57 PMThat's what I'm specifying, as posted above
Hobie Chhina
06/15/2023, 9:57 PMCorrect
Hobie Chhina
06/15/2023, 9:57 PMI have the segments in that interval
b
Ben Krug
06/15/2023, 9:57 PMIf you mark as unused in GUI, then issue kill in GUI, this is what happens?
h
Hobie Chhina
06/15/2023, 9:57 PMI created a datasource from the packaged tutorial
Hobie Chhina
06/15/2023, 9:58 PMYepp, that's the problem mate.
Hobie Chhina
06/15/2023, 9:58 PMCheck out the timestamp on the log output
Hobie Chhina
06/15/2023, 9:58 PMDoesn't make any sense
Hobie Chhina
06/15/2023, 9:58 PM1000 01 01
b
Ben Krug
06/15/2023, 9:59 PM😞 I wonder if it's some kind of overflow. Do you need the other segments (ie, the datasource)? If not, maybe a "mark all segments unused", etc, would work?
h
Hobie Chhina
06/15/2023, 10:00 PMYepp that works, if I mark all as unused and then kill, it wipes out the datasource and all of the data is deleted from the deep storage
b
Ben Krug
06/15/2023, 10:00 PMWhich tutorial is this? If this is what it does, maybe the tutorial needs to get fixed.
h
Hobie Chhina
06/15/2023, 10:00 PMI'm wondering whether there's something in the config I can look at
Hobie Chhina
06/15/2023, 10:00 PMSo basically I used the tutorial stuff to create a datasource with 24 hourly segments.
b
Ben Krug
06/15/2023, 10:00 PMI'm not sure about the config. I thought of using API instead of GUI, but I have a feeling the same thing might happen.
h
Hobie Chhina
06/15/2023, 10:01 PMProlly, I'm gonna have to look into the config and setup.
Hobie Chhina
06/15/2023, 10:02 PMThere's something amiss
b
Ben Krug
06/15/2023, 10:03 PMWhich tutorial is it?
h
Hobie Chhina
06/15/2023, 10:03 PMAh actually I'm referring to the tutorial folder under the druid install path
Hobie Chhina
06/15/2023, 10:05 PMThere's a wikipedia data tar.gz file one can use as input data and then copy one of the json files to run an ingestion workload to create a datasource
Hobie Chhina
06/15/2023, 10:05 PMBut regardless, when I set up retention rules and issue a kill task it should remove the segment and wipe out the data
Hobie Chhina
06/15/2023, 10:07 PMHave you played around with that feature? Maybe I'm missing something out
b
Ben Krug
06/15/2023, 10:12 PMIt should work, I don't know why the kill task is changing the interval like that. I suspect the year is too big, I'll play around and check it out, maybe file a bug. (Or, if you have the json and ingestion spec, feel free to create a bug report.) Maybe the ingestion spec isn't handling the input timestamp format correctly, causing weird years.
h
Hobie Chhina
06/15/2023, 10:13 PMSounds good mate. I'll try it out with a few tweaks to see whether I can go beyond this. Let me share the ingestion spec here.
Hobie Chhina
06/15/2023, 10:15 PMThanks for helping out 🙌
