Subject [jira] [Commented] (APEXCORE-222) Delegate Buffer Server purge to StreamingContainer
Date Tue, 14 Jun 2016 21:28:30 GMT

Pramod Immaneni commented on APEXCORE-222:
------------------------------------------

Shouldn't this be an option because bufferserver can be shared between multiple containers
and can also exist outside the streaming container.

> Currently the purge requests are sent to the buffer servers from the app master. This
interaction exists parallel to the heartbeat protocol. Instead, the committed window ID that
is propagated through the heartbeat response can be used in StreamingContainer to initiate
the purge with the local buffer server, similar to how the committed callback on the operator
occurs.
