Donald,
Thanks for the share! Awhile ago, I stumbled across leveldb and I also
pondered the ability to support reverse scanning as a first class feature
in Accumulo. The numbers on that ticket are not surprising, however- we'd

I agree about Dr. Kepner's class.
The D4M software is open source. Please read the license. The home

You can use the schema without Matlab. One example is at
https://github.com/medined/D4M_Schema. You could load data using the
techniques from that
