Genady, Have you read the HBase wiki and BigTable paper?
http://wiki.apache.org/hadoop/Hbase/HbaseArchitecture http://labs.google.com/papers/bigtable.html I believe what you're talking about is multiple columns in a single row, which is really just 2 dimensional. The third dimension comes from the ability to also have multiple versions of each individual column. In your example, you would just have a simple schema with a single column family. That family can store any number of columns for each row (0 to many thousands, or soon millions). Take a look at the above documents, they should help you get an idea of how data is stored in HBase. Looking at what Exelate does, HBase could be a very good fit, I'm storing similar types of data with success.
