Hi,
We want to use Cassandra to store camera detection. The size of a picture +
data is about 0.5MB. We starting with 5 devices, but we targeting 50 device for
the next year, and could go up to 1000. I summary everything ,
* Number of sources: 5 - 50 - 1000 (src)
* Frequency of data: 1Hz (f)
* Estimate size of data: 0.5MB (s)
* Replication factor: 3 (RF)
I calculated the size per year,
* src * f *60 * 60 * 24 * 365 * s
gives me,
* 5 sources = 0.24 PB per year
* 50 sources = 2.4 PB per year
* 1000 sources = 47.3 per year
so if respect the 2TB rule, I got, 120 nodes in the simplest case (5 sources).
Am I right ?
regards,
Nicolas Jäger
