After 9 months' development, we are happy to announce a new version of RisingLight. Major changes in this version:

  • New cascades-style binder / planner / optimizer framework powered by egg.
  • New SIMD expression evaluation design with better performance.
  • More efficient storage with better encoding and predicate push-downs.
  • Better docs on the storage layer.

Thanks for your support!
