Hey Guys,
How can I define custom CQL3 functions (similar to dateOf, now, etc)?
You can't, there is currently no way to define custom functions.

This /is/ our first cluster. We've upgraded one-over-one since 2.0.2 (our
initially deployed version), doing rolling updates across the rings.
No especial resource tuning save turning off SELinux and the usual (disabling
swap, separate disk for commit logs, data and the OS).

I’m wondering if write consistency “ALL” on the KeySpace will help, here. I

Subject: Re: Adding a node to cluster keeping 100% data replicated
Hi,
I have two tables and I enabled row caching for both of them using CQL. These
two CF's are very small with one about 300 rows and other 2000 rows. The rows
themselves are small.
Cassandra heap: 8gb.
a. alter table TABLE_X with caching = 'rows_only';
b. alter table TABLE_Y with
I am trying to bring up a 6 node cluster in AWS. 3 seed nodes and 3
non-seed nodes. One of each in each availability zone with 1.2.15 and my
non-seed nodes never join the cluster. If I run 1.2.14 everything works
fine. We are not using vnodes and all of the initial_token values are
assigned based

@Mullen,
I think your diagram does not answer the question on responses.
@Sameer
All nodes in DC2 will replay back to the co-ordinator in DC1. So if you
have replication of DC1:3,DC2:3. A co-ordinator node will get 6 responses
back if it is not in the replica set.
Hope that answers your question.
Hello,
Please paste the output of cfhistograms for these tables. Also, what
does your environment look like, number of nodes, disk drive configs,
memory, C* version, etc.
Thanks,
Jonathan

Looks like #6685 was committed to the cassandra-1.2 branch, yesterday.
SNAPSHOT artifacts can be grabbed for the latest build of each
So is that picture incorrect, or just incomplete missing the piece on how
the nodes reply to the coordinator node.

1. reply part is missing.
2. It is confusing a little bit. I would not use term synchronous.
Everything is asynchronous here. Coordinator writes data to all local nodes
and waits for response from ANY two of them (in case of quorum). In your
picture it looks like the coordinator first makes

The picture shows a sample request, which is why the coordinator points to
two specific nodes. What I was trying to convey that the coordinator node
would ensure that 2 of the 3 nodes were written to before reporting success
to the client.

This is my point. ANY 2 of 3. Your picture shows
slightly off topic, but does anyone know off the top of their head what happens
if data is being written at LOCAL_QUORUM to a multi data center setup faster
than the inter data center link can handle… something has to block, throw an

The same problem happens with the non-mobile page:

I think the issue you're running into is the same reason not to compose a
script or config file in notepad. Without using a true text editor (vi), or
relying on copy and past, you're very likely to introduce non visible
formatting characters, as you see with you paragraph symbols. Trusting code
