Yingjie Cao created FLINK-18762: ----------------------------------- Summary: Make network buffers per incoming/outgoing channel can be configured separately Key: FLINK-18762 URL: https://issues.apache.org/jira/browse/FLINK-18762 Project: Flink Issue Type: Sub-task Components: Runtime / Network Reporter: Yingjie Cao Fix For: 1.12.0
In FLINK-16012, we want to decrease the default number of exclusive buffers at receiver side from 2 to 1 to accelerate checkpoint in cases of backpressure. However, number of buffers per outgoing and incoming channels are configured by a single configuration key. It is better to make network buffers per incoming/outgoing channel can be configured separately which is more flexible. At the same time, we can keep the default behavior compatible. -- This message was sent by Atlassian Jira (v8.3.4#803005)
