>
> Currently, the streaming endpoint creates a metastore client which gets used 
> for RPC. The client itself is not internally thread safe. Therefore, the API 
> methods should provide the relevant synchronization so that the methods can 
> be called from different threads. A sample use case is as follows:
> 1. Thread 1 creates a streaming endpoint and opens a txn batch.
> 2. Thread 2 heartbeats the txn batch.
> With the current impl, this can result in an "out of sequence response", 
> since the response of the calls in thread1 might end up going to thread2 and 
> vice-versa.
