Vihang Karajgaonkar commented on HIVE-23018:
--------------------------------------------
Attached the first version of the patch. The patch adds new fields to the
{{InsertEventRequestData}} and {{FireEventRequestData}} to optionally give the
ability to clients to send multiple {{InsertEventRequestData}} for individual
partitions in one RPC call.
> Provide a bulk API to fire multiple insert events

> Metastore provides a API to fire a listener event (currently only supports
> INSERT event). The problem with that API is that it only takes in one
> partition at a time. A typical query may insert data into multiple partitions
> at a time. In such a case query engines like HS2 or Impala will have to issue
> multiple RPCs to metastore sequentially to fire these events. This can show
> up as a slowdown to the user if the query engines do not return the prompt to
> the user until all the events are fired (In case of HS2 and Impala). It would
> be great if we have bulk API which takes in multiple partitions for a table
> so that metastore can generate many such events in one RPC.
