swy updated FLINK-9597: ----------------------- Attachment: scaleNotWork.png > Flink fail to scale! > -------------------- > > Key: FLINK-9597 > URL: https://issues.apache.org/jira/browse/FLINK-9597 > Project: Flink > Issue Type: Bug > Components: Core > Affects Versions: 1.5.0 > Reporter: swy > Priority: Major > Attachments: scaleNotWork.png > > > Hi, we found that our Flink application with simple logic, which using > process function is not scale-able when scale from 8 parallelism onward even > though with sufficient resources. Below it the result where is capped at > around 250k TPS. No matter how we tune the parallelism of the operators it > just not work, same to increase source parallelism. > Please refer to "scaleNotWork.png", > 1. fixed source parallelism 4, other operators parallelism 8 > 2. fixed source parallelism 4, other operators parallelism 16 > 3. fixed source parallelism 4, other operators parallelism 32 > 4. fixed source parallelism 6, other operators parallelism 8 > 5. fixed source parallelism 6, other operators parallelism 16 > 6. fixed source parallelism 6, other operators parallelism 32 > 7. fixed source parallelism 6, other operators parallelism 64 -- This message was sent by Atlassian JIRA (v7.6.3#76005)
