complexity of get(key) and get(key, column) operations

[Claudio Martella <cl...@tis.bz.it>]

 Hello list,


what is the complexity of specific row and specific row/column with
sstable files? Is it O(1)? i'm considering the idea of putting a graph
in cassandra's datamodel and i'd like to follow n-length paths in n*O(1).

the idea is to create a column family where i store vertices with their
properties as columns and a column family where i store the vertices
with in-edges and out-edges as columns.

Can somebody comment about this?

TIA

Claudio
