some suggestions below... but overall, you've done a great job writing up
complicated documentation!

> Implement multi-active, non blocking for leader host
> ----------------------------------------------------
>
> Key: GOBBLIN-1837
> URL: https://issues.apache.org/jira/browse/GOBBLIN-1837
> Project: Apache Gobblin
> Issue Type: Bug
> Components: gobblin-service
> Reporter: Urmi Mustafi
> Assignee: Abhishek Tiwari
> Priority: Major
> Time Spent: 9h 10m
> Remaining Estimate: 0h
>
> This task will include the implementation of non-blocking, multi-active
> scheduler for each host. It will NOT include metric emission or unit tests
> for validation. That will be done in a separate follow-up ticket. The work in
> this ticket includes
> * define a table to do scheduler lease determination for each flow's trigger
> event and related methods to execute actions on this table
> * update DagActionStore schema and DagActionStoreMonitor to act upon new
> "LAUNCH" type events in addition to KILL/RESUME
> * update scheduler/orchestrator logic to apply the non-blocking algorithm
> when "multi-active scheduler mode" is enabled, otherwise submit events
> directly to the DagManager after receiving a scheduler trigger
> * implement the non-blocking algorithm, particularly handling reminder
> events if another host is in the process of securing the lease for a
> particular flow trigger
