> Allow for longer normalized keys
> --------------------------------
>
> Key: FLINK-1292
> URL: https://issues.apache.org/jira/browse/FLINK-1292
> Project: Flink
> Issue Type: Improvement
> Components: Local Runtime
> Affects Versions: 0.8-incubating
> Reporter: Stephan Ewen
> Fix For: 0.8-incubating
>
>
> The normalized key sorter currently has a hardwired limit of a normalized key
> size of 8 bytes. This still comes from the "single key" era.
> For composite keys, this length is easily exceeded and sorts cannot happen as
> fast as the could. On the other hand, setting the value arbitrarily large
> impacts memory consumption.
> I propose to extend this to allow for 8 bytes per key up to a total length of
> 16 bytes. This fits at least two composite longs, or a sequence of Ints.
