From Pydantic V1 to V2
summary
Pydantic v2 splits into a pure-Python layer that emits a nested core schema dict and a Rust-backed pydantic-core (Rust) library that compiles that schema into a schema validator object, giving benchmarks up to 17x performance gains; most validation runs in Rust. Trade-offs: faster and more maintainable but cyclic models can cause stack overflows, Rust APIs feel verbose, and migration is eased by vendoring v1 as pydantic.v1 while you progressively update imports.
