you'd be able to write them atomically
To clarify, this is only the case if you use Cassandra 2.0 transactions; normal batched writes are not atomic in the sense you're probably thinking.
- iamaleksey 13y agoNo batching here, just single-partition, two cell update. Atomic, but not isolated in the way you define isolation in your gist.
- cbsmith 13y agoActually, even in Cassandra 1.2, batch operations were atomic unless otherwise specified.
- jeremiahjordan 13y agoThey are atomic, they are not isolated. Those are two different properties. The "A" vs the "I" in ACID. http://en.wikipedia.org/wiki/ACID http://en.wikipedia.org/wiki/ACID Edit: Actually, they are isolated in the sense of ACID, doesn't matter what order you do to operations, the answer will be the same. But not isolated the way you want isolated described.
