If you still have problems send through some details of where you get incorrect results.

Using thrift and get_range_slices call with tokenrange. Using Random Partionioner. Have only tried this on > 0.7.5
Used to work in 0.6.4 or earlier version for me , but I notice that it does not work for me anymore. The need is to iterate over a token range to do some bookkeeping.
The logic is use
- TokenRange from describe_ring
- and then for each range
- set the start and end token
- get a batch of rows using get_range_slices
- Then use the last token from the batch to set the start_token and repeat (get the next batch). iterate until no more to get (or last from new batch is same as last from previous batch)
Now this works when in a test I insert n records and then for iterating use a batch size m such that m > n. As soon as I use m < n, I get incorrect count or an infinite loop where the range seems to repeat.
Anybody seen this issue or am I using it incorrectly for newer versions of cassandra? I will also look up how this is done in Hector, but in the meantime if somebody has seen this behavior, please do respond.
