Change subject: IMPALA-6645: Enable disk spill encryption by default ...................................................................... IMPALA-6645: Enable disk spill encryption by default Perf: Targeted benchmarks with a heavily spilling query on a machine with PCLMULQDQ support show < 5% of CPU time spent in encryption and decryption. PCLMULQDQ was introduced in AMD Bulldozer (c. 2011) and Intel Westmere (c. 2010). Testing: Ran core tests with the change. Updated the custom cluster test to exercise the non-default configuration.
