Thanks for the kind words! At the moment the query language transpilation is quite unstable but we are in the process of a large remodel which we aim to finish in the next day or so. This will make the query language compilation far more robust, and will return helpful error messages (like the rust compiler). The other thing is the core traversals are currently single threaded, so aggregating huge lists of graph items can take a bit of a hit. Note however, that we are also implementing parallel LMDB iterators with the help of the meilisearch guys to make aggregation of large results much faster.
