Hi. I'm fairly new to the graph world. so far have only relied on a sigmajs based debugging visualization driven by realtime events ( distributed networking integration / debugging context ). I'm exploring the possibilities regarding persisting data too. looked at kuzu ( Fully awar it has a totally different scope that this project ) and recently found nebula. Was wondering if there are any "streaming / live query" concepts in a database like nebula? I'm basically trying to find a good match for an erlang based system with many "graph like" concepts like supervision trees, message passing, ... and the distributed and opensource characteristics of nebula is what catched my attention. not so sure about the query language though. is nebula the only product using it? or is nGQL based on some "underlying" standard?

nGQL introduces its own unique syntax while maintaining compatibility with openCypher. You can find more information here: https://docs.nebula-graph.io/3.8.0/3.ngql-guide/1.nGQL-overview/1.overview/
