> In DDB Streams connector, while testing we found out that when we are 
> spending a lot of time in markAsFinished function because we are calling 
> splitsAvailableForAssignment which is O(N), and given n shards can be marked 
> as finished concurrently, the algorithm becomes O(n^2). Change the algo to 
> assign only child shards when a parent is finished. We can start tracking 
> child shards of a shard in SplitTracker
