we really need to know what the file history is.
if it's a freshly flushed file, that's Bad.
if it's a file that was a compaction victim, that's annoying but not
something we need to worry about.
both flush and compaction are logged at INFO.

yes counts will be a big part of the project (user points). ok i'll wait

thanks!

If you are running multiple datacenters, intend to have a lot of writes for
counters, I highly advise against it. We got rid of ZK because of that.

I can't put data into Cassandra.
I look into the code, for
StorageService.instance.getNaturalEndpoints(keyspace, key) can't get any
InetAddress endpoint
I have start the Cassandra Server in my pc.

Can someone quickly go over how you go about using zookeeper if you want to
store counts and have those counts be accurate?
e.g. in digg's case I believe, they are using zookeeper so they can keep
track of digg's for a particular digg story.
Is it a backend change only and then storing API calls
I think you are correct, David. What Bill is asking for specifically
is not in the API.
Bill,
if this is a performance concern (i.e., your column values are/could
be vastly larger than your column names, and you need to query the
namespace before loading the values), then you might consider keepin
Not in Cassandra.
Your description of the levels is not quite accurate, either. The
keyspaces and CFs are generally considered fixed since it is rather
expensive to change them compared to the row keys and columns. Within
an SCF, you have:
row_key: {supercolumn1: {column1A: value1A, column1B: v
Hadoop doesn't make any assumptions about how input source data is
distributed. It can't 'know' that the data for the first 30 splits emitted
by the InputFormat are all stored on the same cassandra node.
The new case with the patch is CASSANDRA-1096

it doesn't like the the int(port) call. somehow the port # isn't
getting through?
I hardcoded the port to 9160, and it works.
Does chiton handle all the column types for display?
I'm assuming it doesn't show mixed type column names (e.g. first x
bits are a long, and the rest is a text utf-8)?
thanks for the help. I had two versions of python, it was using the wrong one.
I got the GUI to show up, but when i connect by going to file/connect
and enter localhost/9160... i get the following in the output:

What do you mean it didn't work?
CassandraBulkLoader is a map/reduce program, so you'll need hadoop setup.

Grepping through the logs, I haven't been able to deduce what was going on

4-23-2010). The files not found include Index and Data files spanning

Bill, I am a new user of Cassandra, so I've been following this discussion
with interest. I think the answer is "no", except for the brute force method
of looping through all your data. It's like asking for a list of all the
files on your C: drive. The term "column" is very misleading, since
"colum
