[jira] [Commented] (HIVE-6721) Streaming ingest needs to be able to send many heartbeats together

Alan Gates commented on HIVE-6721:
----------------------------------

[~rhbutani] This should go into 0.13 as well, as HIVE-5687 will depend on it.

> The heartbeat method added to HiveMetaStoreClient is intended for SQL operations where the user will have one transaction and a hand full of locks.  But in the streaming ingest case the client opens a batch of transactions together.  In this case we need a way for the client to send a heartbeat for this batch of transactions rather than being forced to send the heartbeats one at a time.
