Subject Accumulo as a Column Storage
Date Thu, 19 Oct 2017 21:50:50 GMT
AFAIK in Accumulo we can use "locality groups" to group sets of columns
together on disk which would make it more like  a column-oriented database.
Considering that "locality groups" are per column family, I was wondering
what if we treat column families like column qualifiers (creating one
column family per each qualifier) and assigning each to a different
locality group. This way all the data in a given column will be next to
each other on disk which makes it easier for analytical applications to
query the data.

Any thoughts?
