The main problem with this is that the window trigger only > fires if the new distance has increased by at least 50 but after restore, it > will be reset to 0 and could thus not produce output for a while. > > Either the distance calculation could use {{Math.abs}} or the source needs > proper checkpointing. Optionally with allowing the number of cars to > increase/decrease. -- This message was sent by Atlassian Jira (v8.3.4#803005)
