Jingsong Lee created FLINK-14860: ------------------------------------ Summary: Provide a new InputSplitAssigner that consider page cache utilization ratio Key: FLINK-14860 URL: https://issues.apache.org/jira/browse/FLINK-14860 Project: Flink Issue Type: New Feature Components: Table SQL / Runtime Reporter: Jingsong Lee
At present, only the need of localization is considered in LocatableInputSplitAssigner, but there is a problem of random floating among three copies of split (HDFS has three copies for files), which leads to excessive use of cache. Therefore, we also need to make it possible to schedule three copies in a clear order on the basis of localization. -- This message was sent by Atlassian Jira (v8.3.4#803005)
