I have used Dgraph in my business. it made us amazing.but there is some problems are bothering me.
- dgraph could not support multi database or tenancy in one cluster, it means one business must need one cluster, that makes hardware cost is too high.
- I have a large dataset about 50 billion. it is difficult for us to load it into cluster by bulk loader or live loader(because of oom).
- I want to mutate data in realtime by pipeline like kafka or other streaming processing.currently, dgraph cant not support high throughput very well.
- I do some tests about insert data and modify data. it got lower query throughput after inserting data.I had a discussion(Query throughput),but from now,it is unresolved.
- Now, Dgraph can not support bigdata system.So, it means if I have a large dataset in hive, hdfs and so on, there is no way to load dataset into Dgraph conveniently.
because of the above major obstacles, it is hard for us to large-scale use dgraph in production.
