HBase is a sparse, distributed, persistent multidimensional sorted map. The map is indexed by a row key, column key, and a timestamp; each value in the map is an uninterpreted array of bytes. Applications store rows in labelled tables. A row has a sortable key and an arbitrary number of columns. All rows are sorted in strict alphabetical sequence.
