Motivation
GSQL is a Turing complete Graph Database query language. Compared to other graph query languages, the biggest advantage is its support of Accumulators — global or attachable to each vertex.
In addition to providing the classic pattern match syntax, which is easy to master, GSQL supports powerful run-time vertex attributes (a.k.a local accumulators) and global state variables (a.k.a global accumulators). I have seen users learning and adopting pattern match syntax within ten minutes. However, I also witnessed the uneasiness of learning and adopting accumulators for beginners.
