[jira] [Created] (FLINK-6469) Configure Memory Sizes via units
Stephan Ewen created FLINK-6469:
-----------------------------------
Summary: Configure Memory Sizes via units
Key: FLINK-6469
URL: https://issues.apache.org/jira/browse/FLINK-6469
Project: Flink
Issue Type: Improvement
Components: Core
Reporter: Stephan Ewen
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}}.

10000 -> bytes
10 kb
64 mb
1 gb
