Storage on disk and not in memory
The storage of the data in Relavance is directly on disk, persistent. You don't have to put all the data in memory to use Relavance. 32 GB or 64 GB is enough memory. For very large organizations this is the only way to move forward. This is where other in-memory systems just stop or crash. For those organizations, Relavance is a must.
By the atomic nature of data storage, the performance of the systems is still fast with huge amounts of data. No in-between layers. Data is right on the hard disk which can be fetched with just 4 reads!! That is independent of the amount of data.
