Subject Accumulo database type: columnar?
Date Tue, 24 Mar 2015 19:23:43 GMT
According to Wikipedia:  http://en.wikipedia.org/wiki/Apache_Accumulo Accumulo is a column-oriented
database.   Wikipedia defines column-oriented this way " A column-oriented database serializes
all of the values of a column together, then the values of the next column, and so on."

I understand it is possible to store some column related data together with locality groups
but wouldn't the default behavior be key/value store type database instead of column-oriented?

Thanks,

Sandy
