One of the big questions these days is how AI will change the world of databases and data management. Most databases are still struggling to implement high-quality fuzzy search, and the only kind of joins they know are deterministic. A join differs from searching for every entry, requiring a...

l join汇聚: 所有到达并行网关,在此等待的进入分支, 直到所有进入顺序流的分支都到达以后, 流程就会通过汇聚网关。 注意,如果同一个并行网关有多个进入和多个外出顺序流, 它就同时具有分支和汇聚功能。 这时,网关会先汇聚所有进入的顺序流,然后再切分成多个并行分支。与其他网关的主要区别是,并行网关不会解析...
