Da Zhou created HADOOP-16317: -------------------------------- Summary: ABFS: improve random read performance Key: HADOOP-16317 URL: https://issues.apache.org/jira/browse/HADOOP-16317 Project: Hadoop Common Issue Type: Sub-task Components: fs/azure Affects Versions: 3.2.0 Reporter: Da Zhou
Improving random read performance is an interesting topic. ABFS doesn't perform well when reading column format files as the process involves with many seek operations which make the readAhead no use, and if readAheadĀ is used unwisely it would lead to unnecessary data request. Hence creating this Jira as a reminder to track the investigation and progress of the work. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-dev-h...@hadoop.apache.org
