Okay, here is two ways to handle this, both are quite different from each
other.
A)
This approach does not depend on counters. You simply have a Column Family
with the row key being the Unix time divided by 60x60 and a column key of...
pretty much anything unique. Then have another process look
If you delete a row, and it therefore is marked as tombstone, and
subsequently you try to insert the row again it appears to succeed,
but if you try to request the row you don't get a result.
If you try to insert a row that has been recently deleted, and has an
active tombstone I would expect eith
I'm looking at how to achieve a search on several separate fields.
Before 0.7.0 this would mean separate indexes maintained by explicit
mutations by the client. Recently automatic secondary indexes were
added to 0.7.0. I have several indexes. My index row keys are
composite keys. All the indexes ar
Microsoft has essentially copied the Cassandra approach for it's Table
Storage. See here:

It is I believe a compliment of sorts, in the sense that it is a
validation of the Cassandra approach. The reason I know about this is
that I attended a

Seconded; specifically I was wondering if you can define the secondary

Hi everyone,
I'm trying to to get the beta of 0.7.0 up and running. I have had a
previous build from a couple of weeks ago working okay; one that I
built myself from source.

I know Cassandra 0.7 isn't released yet, but I was wondering if anyone
has used Pelops with the latest builds of Cassandra? I'm having some
issues, but I wanted to make sure that somebody else isn't working on
a branch of Pelops to support Cassandra 7. I have downloaded and built
