----------------------------------
Summary: State API should allow state to be managed in different
windows
Key: BEAM-1261
URL: https://issues.apache.org/jira/browse/BEAM-1261
Project: Beam
Issue Type: Bug
Components: beam-model, sdk-java-core
Reporter: Ben Chambers
Assignee: Kenneth Knowles
For example, even if the elements are being processed in fixed windows of an
hour, it may be desirable for the state to "roll over" between windows (or be
available to all windows).
It will also be necessary to figure out when this state should be deleted (TTL?
maximum retention?)
Another problem is how to deal with out of order data. If data comes in from
the 10:00 AM window, should its state changes be visible to the data in the
9:00 AM window?
