[jira] [Updated] (FLINK-14058) FLIP-53 Fine Grained Operator Resource Management

["Zhu Zhu (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/FLINK-14058?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Zhu Zhu updated FLINK-14058:
----------------------------
    Release Note: 
The memory configs for table operators are weight hints now rather than absolute memory requirements. The configs includes
 * table.exec.resource.external-buffer-memory, 
 * table.exec.resource.hash-agg.memory, 
 * table.exec.resource.hash-join.memory, and
 * table.exec.resource.sort.memory.
In this way, operators would be able to make use of all the managed memory of a slot. It helps the task to run more stable if the slot managed memory is limited, or more efficient if their are adequate slot managed memory.
