Summary: Enhance stateful windowing to persist the window state
Key: STORM-2614
URL: https://issues.apache.org/jira/browse/STORM-2614
Project: Apache Storm
Issue Type: Bug
Reporter: Arun Mahadevan
Assignee: Arun Mahadevan
Right now the tuples in window are stored in memory. This limits the usage to
windows that fit in memory and the source tuples cannot be acked until the
window expiry. By persisting the window transparently in the state backend and
caching/iterating them as need, we could support larger windows and also
windowed bolts with user/application state.
