Hi,
I was reminded that there is a Remove API, which can delete the whole rows
by specifying the timestamp, key, and column family (in this case,
super_column or column are optional).
But I found, even I delete all rows for the specified keys with this method,
the get_range_slices API will
Ideas:
Use a checkpoint that moves forward in time for each logical partition
of the workload.
Establish a way of dividing up jobs between clients that doesn't
require synchronization. One way of doing this would be to modulo the
key by the number of logical workers, allowing them to graze direct
We have implemented a distributed queue (similar to AWS SQS) and a job
queue in Cassandra.

Hi all,
Has anyone written a work-queue implementation using Cassandra?
There's a section in the UseCase wiki page for "A distributed Priority
Job Queue" which looks perfect, but unfortunately it hasn't been
filled in yet.

I believe I have asked before but now that I am really getting into the
weeds with this it seems I am about to go down the MongoDB path... before I
do let me ask again (as I would prefer to stick with Cassandra for this app)
Has anyone implemented geo (long & lat) calculations (distance) using

Hey Steve,
What type of authentication are you looking to do? Cassandra itself doesn't,
as far as I know, support any sort of user setup or authentication so it's

No, if your goal is to end up disabling HH, then you can leave it off on the
0.6.2 servers, and when you upgrade the 0.6.1 servers disable it there, then

I believe that the code I grabbed from git is later than the latest download
published on there then.
Where would I find that code ? is it available to public (aka me :-) ), if
not when would that be.
If its a way off, i think I need a version of git that matches the released
code base.
