Stefan Richter closed FLINK-8674. --------------------------------- Resolution: Fixed Fix Version/s: 1.5.0 Merged in a144d0f77f. > Efficiently handle alwaysFlush case (0ms flushTimeout) > ------------------------------------------------------ > > Key: FLINK-8674 > URL: https://issues.apache.org/jira/browse/FLINK-8674 > Project: Flink > Issue Type: Sub-task > Reporter: Piotr Nowojski > Assignee: Piotr Nowojski > Priority: Major > Fix For: 1.5.0 > > > Changes in data notifications introduced alongside BufferConsumer > significantly degraded performance of 0ms flushTimeout. > > Previously flushing after writing only record, effectively triggered only one > data notification for the sub-partition/channel to which this record was > written. With low latency improvements, this changed and flush is now > triggering data notifications for all of the partitions. This can (and > should) be easily fixed. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
