----------------------------------------
Summary: Decreasing scheduler delay between tasks
Key: AIRFLOW-3607
URL: https://issues.apache.org/jira/browse/AIRFLOW-3607
Project: Apache Airflow
Issue Type: Improvement
Components: scheduler
Affects Versions: 1.10.1, 1.10.0
Environment: ubuntu 14.04
Reporter: Amichai Horvitz
Fix For: 1.10.2
I came across the TODO in airflow/ti_deps/deps/trigger_rule_dep (line 52) that
says instead of checking the query for every task let the task report to the
dagrun. I have a dag with many task and delay between tasks can rise to 10
seconds or more, I already changed the configuration, added processes and
memory, checked the code and did research, profiling and other experiments. I
hope that this will make a drastic change in the delay. I would be happy to
discuss this solution, the research and other solutions for this issue.
Thanks
