Five-component architecture adds output enforcement to standard RAG pipelines.
This actually simulates the full write path — WAL to memtable to immutable flush — and animates cascading leveled compactions so you can watch key movement and file counts in real time. The live bloom-filter checks and amplification metrics are the parts that will teach you something immediately; it's clearly built as a learning/debugging sandbox rather than a production profiler.
Paid book about DSPy when Stanford's own docs and tutorials already exist for free.
This repo literally turns CPython internals into rows and stored procedures: object rows, regproc type slots, and an interpreter loop (py_eval_frame) that dispatches opcode handler functions in SQL. It's a clever, hands-on exploration — 103 SQL files, a REPL and 87 tests show serious follow-through — but it's primarily an impressive engineering demo rather than a practical production runtime.
Interactive simulations explain cooperative auctions for rent splitting and resource allocation.
