Add `@Deprecated`
> Configure Memory Sizes with units
> ---------------------------------
>
> Key: FLINK-6469
> URL: https://issues.apache.org/jira/browse/FLINK-6469
> Project: Flink
> Issue Type: Improvement
> Components: Core
> Reporter: Stephan Ewen
> Assignee: vinoyang
> Priority: Major
>
> Currently, memory sizes are configured by pure numbers, the interpretation is
> different from configuration parameter to parameter.
> For example, heap sizes are configured in megabytes, network buffer memory is
> configured in bytes, alignment thresholds are configured in bytes.
> I propose to configure all memory parameters the same way, with units similar
> to time. The JVM itself configured heap size similarly: {{Xmx5g}} or
> {{Xmx2000m}}.
> {code}
> 10000 -> bytes
> 10 kb
> 64 mb
> 1 gb
> ...
> {code}
