Alec Ryan
04/26/2022, 11:11 PMJob 1 (partitioned) runs, kicks off job 2 which runs and then kicks off job 3
Alec Ryan
04/26/2022, 11:12 PMI need to backfill job 1 and kick off jobs 2 & 3 for each partition run

04/27/2022, 5:46 PMYou can have the partitioned job launch off a materialization at the end of each run, which you can use to trigger the next jobs in sequence using an asset sensor: https://docs.dagster.io/concepts/partitions-schedules-sensors/sensors#asset-sensors

04/27/2022, 5:48 PMHey Chris, that is what I am currently doing
Alec Ryan
04/27/2022, 5:48 PMMy issue is the second and third job don't run for every partition backfill

chris
04/27/2022, 5:50 PMhmm how often is the sensor firing? Are you logging a partitioned asset materialization?

Alec Ryan
04/27/2022, 6:00 PMYes, the first job logs the partitioned asset materialization.
Alec Ryan
04/27/2022, 6:00 PMThe second job does not fire though

chris
04/27/2022, 6:30 PMHmm asset sensors should fit your use case here. Are you sure that the asset sensor is actually firing?

Alec Ryan
04/28/2022, 12:08 PMI thought so... How would I check that?
Alec Ryan
04/28/2022, 12:08 PMThey don't run (which is my problem) so I guess they don't

chris
04/28/2022, 4:32 PMThere should be a tick history on the page for the sensor in dagit.

04/28/2022, 4:41 PM(Also, make sure that the daemon is actually on, and the sensor is switched on)
