No difference in the way data is displayed, aggregated, analyzed, searched on Germain dashboard.


Performance of Germain is significantly better than relational database and you will find it more obvious once you start reaching ~500 Millions metrics stored DAILY in Germain (yet you can start seeing performance benefit at 100 or 200 Million Germain unit per day for low-end hardware and storage).


~200 Million Germain Units are stored on this environment where this screenshot was taken from and every navigation takes less than a second.
