Columnstores can do row level access by trading off a bit in terms of compression. If you organize the columnstore files as an LSM tree and use incremental compression schemes (so you don't have to compress too many more rows then the one your after) it can get close to the performance of a B-Tree for point reads - it depends on the specific table schema.
