Gyula Fora created FLINK-1617:
---------------------------------
Summary: GSoC project: Query optimisation layer for Flink Streaming
Key: FLINK-1617
URL: https://issues.apache.org/jira/browse/FLINK-1617
Project: Flink
Issue Type: New Feature
Components: Streaming
Reporter: Gyula Fora
Flink streaming currently only supports a limited set of optimisations applied
on the streaming programs such as operator chaining, and several optimisations
for windowing computations.
The goal of this project would be to extend the optimiser functionality to
include other available query optimisation techniques. This would be a critical
feature in the system as it could potentially bring major performance
improvements depending on the query.
A comprehensive list of optimisation techniques for streaming queries can be
found here:

New ideas are also very welcome, the possibilities are endless.
