Guozhang Wang updated KAFKA-5285: --------------------------------- Labels: performance (was: ) > optimize upper / lower byte range for key range scan on windowed stores > ----------------------------------------------------------------------- > > Key: KAFKA-5285 > URL: https://issues.apache.org/jira/browse/KAFKA-5285 > Project: Kafka > Issue Type: Improvement > Components: streams > Reporter: Xavier Léauté > Assignee: Xavier Léauté > Labels: performance > > The current implementation of {{WindowKeySchema}} / {{SessionKeySchema}} > {{upperRange}} and {{lowerRange}} does not make any assumptions with respect > to the other key bound (e.g. the upper byte bound does not depends on lower > key bound). > It should be possible to optimize the byte range somewhat further using the > information provided by the lower bound. > More specifically, by incorporating that information, we should be able to > eliminate the corresponding {{upperRangeFixedSize}} and > {{lowerRangeFixedSize}}, since the result should be the same if we implement > that optimization. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
