One of the advantages Accumulo has over other databases is its use of cell level security. Most of the other databases have only column level security so a user can either see a value for a key or not. Having the security down to the cell level will allow a user to see different values as appropriate based on the row.8 Mar 2016
How does Accumulo work?
Accumulo stores data in tables, which are partitioned into tablets. As clients insert and query data, and as machines are added and removed from the cluster, the Master migrates tablets to ensure they remain available and that the ingest and query load is balanced across the cluster.
