I agree that talking about JIT compilation (or just-in-time compilation) would be better than talking just about JIT, but refusing to mention JIT seems counter-productive to me. There are a lot of people who know what just-in-time compilation is and will not realize that "compilation of expressions" refers to any such technology. If you don't know what it is, you can Google it. Just typing "jit" into Google produces a stupid urban dictionary hit and then this: https://en.wikipedia.org/wiki/Just-in-time_compilation -- and that contains useful information that you'll never find if you search for "compilation of expressions". Also, in a way, you could argue that v10 already did "compilation of expressions". It didn't compile them to machine language, true, but it translated them into a form which is faster to execute, and which is at least arguably a form of bytecode. It's not going to be clear, even to an expert, that "compilation of expressions" means something other than that, but if you say JIT, then all of a sudden people know what we're talking about. I agree that JIT is jargon, but it's pretty commonly-used jargon. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
