I'm using QUORUM, but in my single-node setup this doesn't matter IMHO.

Which ConsistencyLevels did you use for your batchMutate() and

ConsistencyLevels directly dictate the level of consistency you will
get with your data.

Hi,
I'm performing tests with Cassandra 0.6.5 with Hector 0.6.0-14 on
a single machine (one node cluster). I've noticed an issue with
consistency.
In my tests I perform a KeySpace.batchMutate() to update a column
and immediately after that I perform a KeySpace.getSlice() on the
same column (from within the same thread). I noticed that
occasionally I get back the previous value rather than the value
I've just written.
My guess is that this occurs because Hector uses pooled
connections and both my requests are executed on different
connections. I suspect this causes a race condition in Cassandra
between the getSlice() and the batchMutate().
Can anyone confirm my suspicions and does anyone have a solution
for this?
Groets, Hugo.
