Edward Zhang created EAGLE-410:
----------------------------------
Summary: stream tumbling window aggregate library
Key: EAGLE-410
URL: https://issues.apache.org/jira/browse/EAGLE-410
Project: Eagle
Issue Type: Task
Affects Versions: v0.5.0
Reporter: Edward Zhang
Assignee: Edward Zhang
Fix For: v0.5.0
Many use cases need aggregate data in streaming process, but Storm does not
provide high level aggregation API. The most frequently used example is to
aggregate data per minute while data is streamlined.
After investigation, we found Siddhi CEP engine is good for this task.

This ticket will develop a preview of simple aggregation API for Eagle use case.
