Instead of a continuous stream, the electron beam is divided into nanosecond-long bunches—billions of electrons riding the radio-frequency field like surfers. Inside the accelerator’s cavities, the field flips polarity 12 billion times per second, so timing is everything: Only electrons that arrive perfectly in phase with the accelerating wave will gain energy. That process repeats through a chain of cavities, each giving the bunches another push, until the beam reaches its final energy of 200 MeV.

ClickHouse has full JOIN support with all standard SQL join types, plus specialized variants like ANY, ASOF, SEMI, and ANTI joins that can significantly improve performance for common analytical patterns. That said, joins are inherently memory-intensive operations, and understanding the tradeoffs between different approaches is key to avoiding memory issues.
