Neelesh Srinivas Salian commented on FLINK-10619:
-------------------------------------------------
having a look at MemoryStateBackend, the javadoc says this and it seems like
this isn't needed.
{code:java}
* <h1>Configuration</h1>
*
* <p>As for all state backends, this backend can either be configured within
the application (by creating
* the backend with the respective constructor parameters and setting it on the
execution environment)
* or by specifying it in the Flink configuration.
*
* <p>If the state backend was specified in the application, it may pick up
additional configuration
* parameters from the Flink configuration. For example, if the backend if
configured in the application
* without a default savepoint directory, it will pick up a default savepoint
directory specified in the
* Flink configuration of the running job/cluster. That behavior is implemented
via the
* {@link #configure(Configuration)} method.

> The default MAX_STATE_SIZE of MemoryStateBackend is 5 * 1024 * 1024.
> If we want to change it, the only way is
> {code:java}
> // code placeholder
> env.setStateBackend(new MemoryStateBackend(1024 * 1024 * 1024));{code}
> Is it?
> So shall we add it into configuration file?
