August Product Updates

The summer is winding down, but our team has been hard at work on a new release and some other goodies. Here’s what we’ve been up to this month:

What’s New

• Expanded query support
  • IN and NOT IN expressions with subqueries on the right-hand side in the projected field list (07ef2a8)
  • WHERE clause containing NOT IN with subqueries on the right-hand side (3c87547)
  • WHERE clause containing IN with subqueries on the right-hand side (380b258)
• Performance & memory usage optimizations
  • Improved performance of Postgres cached query response encoding (e662a9d)
• Usability improvements
  • Better error message and guidance for passwords that include special characters (e166f17)
  • --query-log and --query-log-ad-hoc are now enabled by default if --prometheus-metrics is set, effectively enabling all query metrics by default if metrics are enabled (66b4a54)
