>
> The current implementation of 'creating intermediate streams' depends on
> leader election, followed by the leader creating the intermediate streams. We
> have removed this dependency on leader election and changed the Latch
> interface to a generic Lock interface. Following this, any processor that
> acquires the lock can create the intermediate streams, irrespective of
> whether it is the leader or not. It releases the lock after successful
> creation of the streams.
