Yesterday I build a timeserie solution for Stedin based on Phoenix and NiFi.
Processing timeseries is always difficult because of the streaming characteristics of timeserie data combined with the need of aggregation over time windows.
Phoenix offers you this functionality combined with the speed of HBase and the aggregation power of Hive. NiFi adds the flexibility of dataflows to this solution.
Combining a secure Phoenix system with NiFi needs a workaround as described in the article below.
