Q The language of God!
summary
Overview of Q and kdb+ with concrete numbers and demos: shows native binary serialization that takes ~2 ms for 1M integers versus JSON 2.7 s, a WebSocket round‑trip that parses to JSON in ~760 ms, and batched writes that can hit ~333 million inserts/sec (examples on single machine and multicore by running 159 q processes to partition 159M rows). Uses WebSockets, the -8 binary wire format, a canvas-based hypergrid to render 24,309 rows in 88 ms end-to-end, and explains k (C bootstrapped q) and CEP/streaming patterns used in finance.
