--------------------------------
Summary: Refactor the constructor of NetworkEnvironment
Key: FLINK-12067
URL: https://issues.apache.org/jira/browse/FLINK-12067
Project: Flink
Issue Type: Sub-task
Components: Runtime / Network
Reporter: zhijiang
Assignee: zhijiang
The constructor of {{NetworkEnvironment}} could be refactored to only contain
{{NetworkEnvironmentConfiguration}}, the other related components such as
{{TaskEventDispatcher}}, {{ResultPartitionManager}}, {{NetworkBufferPool}}
could be created internally.
We also refactor the process of generating {{NetworkEnvironmentConfiguration}}
in {{TaskManagerServiceConfiguration}} to add {{numNetworkBuffers}} instead of
previous {{networkBufFraction}}, {{networkBufMin}}, {{networkBufMax}}.
Further we introduce the {{NetworkEnvironmentConfigurationBuilder}} for
creating {{NetworkEnvironmentConfiguration}} easily especially for tests.
