Accumulo Data Storage Efficiency

[David Medinets]

Are there any published numbers for the amount of disk space used by
Accumulo versus other products? I'm thinking some dataset like dbpedia
or something from http://books.google.com/ngrams/datasets. If there is
not such a comparison, what comparisons would you like to see? What
about WordNet stored in CSV, MySQL, Cassandra, HBase, and Accumulo?
WordNet is just a large set of CSV files so it would be a good
candidate for this concept, I think.
