Hi All, I'm using Cassandra 1.0.3 (with Hector 0.7). What is the granularity of atomic read and write operations with Cassandra. I.e. is the insert or update of an individual column an atomic operation (in the sense that it either fails or persists completely), or is the insert or update of an entire row in a ColumnFamily atomic?
Similarly, if I read multiple columns of the same row, could the read operation interfere with a concurrent write operation on these same columns in a way that I might see some old and some new column values? Cheers and thanks a lot for any kind help on this! Chris
