Jim Apple created IMPALA-6219:
---------------------------------
Summary: Use AES-GCM for spill-to-disk encryption when CLMUL
instruction is present and performant
Key: IMPALA-6219
URL: https://issues.apache.org/jira/browse/IMPALA-6219
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Affects Versions: Impala 2.11.0
Reporter: Jim Apple
See parent ticket: IMPALA-6128. AES-GCM can be very fast, but it requires an
instruction that Impala can currently run without (CLMUL) in order to be fast,
so we could dispatch at run-time based on the CPU, using this mode when it is
fast.
