Hi,
I would like to install Apache Cassandra 1.1.4 from RPM. Please share a
link to download rpm for CentOS (x86_64) and (i386).

Answered in the other email as well, cache stats are in nodetool info.
But you also have to set the caching property of the CF. By default it's
keys_only. It should be documented in the cassanra-cli and the CQL docs

HH works to a point. Specifically, it only collects hints for the first hour
the node is down and it has a safety valve to avoid the node collecting hints
getting overwhelmed. Looking at the code it takes a bit for that the trip and
you would get a TimeoutException coming back.
Also when
I would guess that Pelops has called remove() on the Thrift API rather than
remove_counter().
Check the code in Pelops. If you turn server side logging up to DEBUG it will
log remove for the non counter call and remove_counter for the counter one.

Hi,
Need some help on a data modelling question. We're using Hector Datastax
Enterprise 2.1.
I want to associate a list of items for a user. It should be sorted on the time
added. And items can be updated (quantity of the item can be changed), and
items can be deleted.
I can model it like

We've used 'em all and (IMHO)
1) I would avoid Thrift directly.
2) Hector is a sure bet.
3) Astyanax is the up and comer.
4) Kundera is good, but works like an ORM -- so not so good if your
columns aren't defined ahead of time.

playOrm has a raw layer that if your columns are not defined ahead of time
and SQL with no limitations on , =, =, etc. etc. as well as joins being
added shortly BUT joins are for joining partitions so that your system can
still scale to infinity. Also has an in-memory database as well for unit
With playOrm we have been researching partitioning and joining partitions for
OLTP applications which you typically partition per client anyways such that
you can have infinite clients. Naturally, we have been looking at a lot of
nested loop join, block nested loop join, sort merge join, and
Thanks Dean… I hadn't played with that one. I wonder if that would better
fit the bill for the Spring Data Cassandra module I'm hacking on.

I'll poke around.

No problem, if you like SQL at all and don't mind adding a PARTITIONS
clause, we have a raw ad-hoc layer(if you have properly added meta data
which the ORM objects do for you but can be done manually) you get a query
like this
PARTITIONS p('account56') SELECT tr FROM Trades as tr WHERE tr. price
@Brian: You're missing PhpCassa (PHP library)

That said, don't use SuperColumns unless you really really know what
you're doing.

If you didn't see this particular section, you may find it useful:
I think you need another CF as index.
user_itemid - timestamped column_name
Otherwise you can't guess what's the timestamp to use in the column name.
Anyway I would prefer storing the item-ids as column names in the main
column family and having a second CF for the order-by-date query only with
Hi all,
I was wondering if anybody had seen the following behaviour before and
how we might detect it and keep the application running.
We have a 6 node cluster. It seems that one of these nodes forgot about
all but one of the application column families - possibly after a
restart. Then,

Running nodetool resetlocalschema then nodetool repair fixed the problem

Hi all
First off, please let me introduce the setup.
- a balance ring of 6 x C* 1.1.2 in active DC (DC1), 6 in another (DC2);
- keyspace's RF=3 in each DC;
- client talks only to DC1 unless DC1 can't serve the request, in which case
talks only to DC2;
- commit log is being sync
Also when hints are replayed they are sent of as mutations, which may still
be dropped by the target if they are not serviced before rpc_timeout. Sending
nodes throttle their requests so it's unlikely but possible.
My bad there. I thought the mutations were send one way.
