Working as Machine Learning Engineer in projects devoted to text analytics,also owning backend development ,data access using SQL,NoSQL.I have started using GraphDB for my current project .Essentially we are targeting to save our knowledge graph output to graph database.Neo4j is the most used graph db and provides free trainings,community support.
I would be more happy if it provides python API support similar to the support it provides to Java API
Graph database is an exciting technology to work on ,hopefully will get opportunity to other use cases as well.
