-----------------------------------
Summary: Improve normalized keys in composite key case
Key: FLINK-1778
URL: https://issues.apache.org/jira/browse/FLINK-1778
Project: Flink
Issue Type: Improvement
Components: Local Runtime
Affects Versions: 0.9
Reporter: Stephan Ewen
Assignee: Stephan Ewen
Fix For: 0.9
Currently, if we have a key (String, long), the String will take up the entire
normalized key space, without being fully discerning anyways. Limiting the key
prefix in size and giving space to the second key field should in most cases
improve the comparison efficiency.
