Re: [Neo4j] Time Series Data with complex domain model

Hey, I have a very complex domain model which can be perfectly mapped into the neo4j database. OR Mapping is much too complex for the model... The data itself is time series data from multiple sensors which needs to be stored and retrieved (at given timestamps or in given ranges). Are there any
