Nico Kruber created FLINK-10142: ----------------------------------- Summary: Reduce synchronization overhead for credit notifications Key: FLINK-10142 URL: https://issues.apache.org/jira/browse/FLINK-10142 Project: Flink Issue Type: Bug Components: Network Affects Versions: 1.6.0, 1.5.2, 1.7.0 Reporter: Nico Kruber Assignee: Nico Kruber
When credit-based flow control was introduced, we also added some checks and optimisations for uncommon code paths that make common code paths unnecessarily more expensive, e.g. checking whether a channel was released before forwarding a credit notification to Netty. Such checks would have to be confirmed by the Netty thread anyway and thus only add additional load for something that happens only once (per channel). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
