Stephan Ewen created FLINK-2683: ----------------------------------- Summary: Add utilities for heap-backed keyed state in time panes Key: FLINK-2683 URL: https://issues.apache.org/jira/browse/FLINK-2683 Project: Flink Issue Type: Sub-task Components: Streaming Affects Versions: 0.10 Reporter: Stephan Ewen Assignee: Stephan Ewen Fix For: 0.10
Time panes are commonly used for aligned time windows (tumbling and sliding). These utilities would represent the panes with per-pane keyed state. The implementation must support: - Evicting panes efficiently - iterating over the union of all panes' state per key for all keys (computing the window function for all keys) - efficient append the state for a key in a random pane -- This message was sent by Atlassian JIRA (v6.3.4#6332)
