[jira] [Created] (FLINK-10146) numBuffersOut not updated properly
Nico Kruber created FLINK-10146:
-----------------------------------
Summary: numBuffersOut not updated properly
Key: FLINK-10146
URL: https://issues.apache.org/jira/browse/FLINK-10146
Project: Flink
Issue Type: Bug
Components: Metrics, Network
Affects Versions: 1.5.3, 1.6.1, 1.7.0
Reporter: Nico Kruber
Assignee: Nico Kruber
We only enqueue a {{BufferConsumer}} once into the result (sub)partition but Netty may draw and send parts of it independently. {{numBuffersOut}} is, however, only increased when a new buffer is retrieved from the buffer pool, not when an actual buffer is sent via Netty. This metric is thus wrong.
