----------------------------------
Summary: Make all configuration possible via flink-conf.yaml and
CLI.
Key: FLINK-4947
URL: https://issues.apache.org/jira/browse/FLINK-4947
Project: Flink
Issue Type: Improvement
Components: DataStream API
Reporter: Jamie Grier
Fix For: 1.2.0
I think it's important to make all configuration possible via the
flink-conf.yaml and the command line.
As an example: To enable "externalizedCheckpoints" you must actually call the
StreamExecutionEnvironment#enableExternalizedCheckpoints() method from your
Flink program.
Another example of this would be configuring the RocksDB state backend.
I think it important to make deployment flexible and easy to build tools
around. For example, the infrastructure teams that make these configuration
decisions and provide tools for deploying Flink apps, will be different from
the teams deploying apps. The team writing apps should not have to set all of
this lower level configuration up in their programs.
