Joe McDonnell created IMPALA-8428: ------------------------------------- Summary: Add support for caching file handles on s3 Key: IMPALA-8428 URL: https://issues.apache.org/jira/browse/IMPALA-8428 Project: IMPALA Issue Type: Bug Components: Backend Affects Versions: Impala 3.3.0 Reporter: Joe McDonnell
The file handle cache is currently disabled for S3, as the S3 connector needed to implement proper unbuffer support. Now that https://issues.apache.org/jira/browse/HADOOP-14747 is fixed, Impala should provide an option to cache S3 file handles. This is particularly important for data caching, as accessing the data cache happens after obtaining a file handle. If getting a file handle is slow, the caching will be less effective. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
