Maximilian Michels commented on FLINK-2404: ------------------------------------------- The performance impact might differ depending on the JDK. Which one did you use? Did you run the experiment multiple times to get an average or a median time measurement? There should definitely be an impact because a conversion has to be performed. However, the JIT compiler might be able to optimize simple cases. > LongCounters should have an "addValue()" method for primitive longs > ------------------------------------------------------------------- > > Key: FLINK-2404 > URL: https://issues.apache.org/jira/browse/FLINK-2404 > Project: Flink > Issue Type: Bug > Components: Core > Affects Versions: 0.10 > Reporter: Stephan Ewen > Fix For: 0.10 > > > Since the LongCounter is used heavily for internal statistics reporting, it > must have very low overhead. > The current "addValue()" method always boxes and unboxes the values, which is > unnecessary overhead. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
