[jira] [Created] (HDFS-10939) Reduce performance penalty of
encryption zones
Daryn Sharp created HDFS-10939:
----------------------------------
Summary: Reduce performance penalty of encryption zones
Key: HDFS-10939
URL: https://issues.apache.org/jira/browse/HDFS-10939
Project: Hadoop HDFS
Issue Type: Sub-task
Affects Versions: 2.7
Reporter: Daryn Sharp
Assignee: Daryn Sharp
The encryption zone APIs should be optimized to extensively use IIPs to eliminate path resolutions. The performance penalties incurred by common operations like creation of file statuses may be reduced by more extensive short-circuiting of EZ lookups when no EZs exist. All file creates should not be subjected to the multi-stage locking performance penalty required only for EDEK generation.
