Unfortunately, limiting yourself to only what is available in standard SQL is not practical. For example, doing idempotent inserts, insert-or-update, sequences, transactional behavior for DDL, data types, date/time manipulation, etc. T

Installing GPG Tools on Mac sets up gpg-agent automatically and has Mac Keychain support. I use the agent support all the time for signing Maven artifacts (which requires password-less entry due to the way the release plugin works).

The 8x improvement is somewhat misleading as it is based on a single TPC-H query. The other queries from the benchmark seem to show a ~3x improvement: http://vitessedata.com/technology Given that their query engine uses an
