DB Meeting - Parallel Query Evaluation: The Volcano Model Turns 20

I will revisit the seminal 1994 paper [1] by Goetz Graefe that describes the parallel Volcano query evaluation model. I will talk about the power of the Volcano model, its relevance to the hardware landscape today (SSDs, in-memory stores, massively multi-core systems), and the engineering challenges of getting it implemented correctly.[1] Graefe, Goetz. "Volcano -- An Extensible and Parallel Query Evaluation System." IEEE Trans. Knowl. Data Eng., vol 6, no. 1, pp 120-135, Feb. 1994.
