Wanted to add one more thing:
I can also tell that the numbers are not consistent across DRs this way
-- I have a column family with really wide rows (a couple million
columns).
DC1 reports higher column counts than DC2. DC2 only becomes consistent

Hello,
I've started to see a slightly worrying error appear in our logs
occasionally. We're writing at 400qps per machine and I only see this appear
every 5-10minutes.

I am not sure if I should use datastax's DSC or official Debian packages

Hi,
One one of my nodes, the (storage) load increased dramatically (doubled),
within one or two hours. The hints column family was causing the growth. I
noticed one HintedHandoff process that was started some two hours ago, but
hadn't finished. Normally, these processes take only a few seconds, 15

Here is some more information.
I am running full repair on one of the nodes and I am observing strange
behavior.
Both DCs were up during the data load. But repair is reporting a lot of
out-of-sync data. Why would that be ? Is there a way for me to tell
that WAN may be dropping hinted handoff
Hi all, in my very old Cassandra schema (started with 0.6 -- so without
secondary indexes -- and now on 1.0.6) I have a rating&review platform with
about 1 million review. The core of the application is the review that a user

Seems I am impacted by a paging bug in C* 2.0.0 and need to go to 2.0.1.
Is there any estimate for when the (Centos 6/64bit) RPM will be updated?
I'd rather wait than change installation procedure - but it depends on the
timeline for me.

hi,
we have a table that its primary key is uuid type. Now we decide that we
need to use text type as it is more flexible for our application.
#1
is there any downside using text as primary key? any performance impact on
