Tim Armstrong resolved IMPALA-6645. ----------------------------------- Resolution: Fixed Fix Version/s: Impala 3.1.0 Impala 2.13.0 > Consider enabling disk spill encryption by default > -------------------------------------------------- > > Key: IMPALA-6645 > URL: https://issues.apache.org/jira/browse/IMPALA-6645 > Project: IMPALA > Issue Type: Improvement > Components: Backend > Affects Versions: Not Applicable > Reporter: Tim Armstrong > Assignee: Tim Armstrong > Priority: Major > Labels: resource-management > Fix For: Impala 2.13.0, Impala 3.1.0 > > > We currently have integrity checks disabled by default because of the > additional CPU cost. > Now that IMPALA-6219 is in, the integrity checks are cheaper so it may be > worth just paying the cost. We could also consider doing a lighter-weight CRC > checksum, but AES-GCM may be fast enough at 2.3GB/s to do by default. > We should do an experiment to see if there's a major impact on spill-to-disk > perf. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
