Hi,
Let's suppose a column (name+value) is cached in memory, with timestamp T.
1) An update, for this column, arrives with exactly the *same* timestamp, and
the *same* value.
Is the commitlog updated ?
2) An update, for this column, arrives with a timestamp T.
Is the commitlog updated ?

If you've seen Lord of the Rings and can remember the scene where Frodo has to
pass the spider you will be well equipped to understand JMX ports.
The ports are randomly opened…
A common problem with RMI and firewall is that the JMX default agent will not
let you specify which port to use to
No.
CounterColumnType only works with column values, which are not sorted. Sorting
counters while they are being updated is potentially very expensive.
You have a few options:
1) If the list of counters is short (say 100 columns) get all the columns and
sort client side.
2) Run a periodic
You can check the streaming progress with nodetool netstats. That will tell you
what it thinks it is moving.
nodetool ring will also tell you what state the nodes are in.
That said, this looks a little suspicious…

What is strange - when streams for the second repair starts they have the
same or even bigger total volume,
What measure are you using ?

Hi,
I'm experiencing a problem running a suite of integration tests on Windows
7, using Cassandra 1.0.9 and Java 1.6.0_31. A new cassandra instance is
spun up for each test class and shut down afterwards, using the Maven

Hi,
I'm finding very difficult to try to understand how Hadoop and Cassandra
(CDH3u3 and 1.0.8 respectively) splits the work between mappers.
The thing that confuses me is that, for any value of cassandra.input.split.size
I set, I always get 1 (at most 2) mapper per node.
