[jira] [Created] (IMPALA-8428) Add support for caching file handles on s3
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)
