- JIT compilation is in v11. Fuck yea.
- 2 sentence: what's JIT
- JIT compilation of expressions
  - when called from most places
- JIT compilation of deforming
  - when called from within expressions
- quick speedups
- explain analyze (demo and showing JIT taking long)
- generated IR
- profiles
- demonstration of problems:
  - JITed code is still a bottleneck
  - JITing can take quite a long while
    - CPU overhead
    - latency
- Way forward
  - JIT more
    - COPY
    - sorts
    - main query execution
    - ...
  - JIT better
    - remove pointers
    - add more context
  - JIT caching
    - basic: local, remove pointers, hash IR, match on full binary comparison
    - improve: keep pointer to cache in prepared statement
    - improve: allow for shared cache
  - JIT startup:
    - JIT in the background, replace pointers
