> 1.8.0rc Issues
> --------------
>
>                 Key: AIRFLOW-921
>                 URL: https://issues.apache.org/jira/browse/AIRFLOW-921
>             Project: Apache Airflow
>          Issue Type: Task
>            Reporter: Dan Davydov
>            Priority: Blocker
>
> These are the pending issues for the Airflow 1.8.0 release:
> Blockers:
> [~bolke] please merge into the next RC and then remove from the list the 
> issues below once they are merged into master
> - Sub-tasks linked in this JIRA
> - Skipped tasks potentially cause a dagrun to be marked as failure/success 
> prematurely (one theory is that this is the same issue as 
> https://issues.apache.org/jira/browse/AIRFLOW-872)
> Other Issues:
> - High DB Load (~8x more than 1.7) - We are still investigating but it's 
> probably not a blocker for the release - (Theories: Might need execution_date 
> index on dag_run (based on slow process list) OR it might be this query which 
> is long running SELECT union_ti.dag_id AS union_ti_dag_id, union_ti.state AS 
> union_ti_state, count( *) AS count_1
> FR))
