Your proposed model for the table to handle the last query looks good, so I
would stick with that.

Thanks Tyler Hobbs.
We need to capture what are the queries ran by a user in a session and its
time taken. (don't need query plan or so). Is that possible? With
Authenticator we can capture only the session creation right?
Thanks

sstable2json can give you a pretty good idea of the format. Otherwise,
your best option is to read the code, starting with
org.apache.cassandra.io.sstable.SSTableWriter.

Cassandra is designed to allow you to write your own Authenticator pretty
easily. You can just subclass PasswordAuthenticator and add logging where
desired. Compile that into a jar, put it in
Hi,
I read somewhere that the order of columns in the cluster key matters.
Please correct me if I am wrong.
For example,
PRIMARY KEY((prodgroup), status, productid).
Then the below query cannot run,
select * from product where prodgroup='xyz' and prodid 0
But this query can be run:
select *
What you want is something like audit logger like the one provided by DSE ?

Hi there,
I am using C* 2.0.10 and I was trying to add a new node to a
cluster(actually replace a dead node). But after added the new node some
other nodes in the cluster had a very high work-load and affected the whole
performance of the cluster.
So I am wondering is there a way to add a new

Even if you only write to nodes in DC A, if you replicate that data to DC
B, it will have to travel over the WAN anyway? What are you

Hi guys,
We have two DC, we are planning to schedule running nodetool repair weekly,
my question is : nodetool repair is cross cluster or not? it's sufficient
to run it without options on a node or should be scheduled on every node
with the host option.
Thanks
What is the data size of the column family you're trying to fetch with
paging ? Are you storing big blob or just primitive values ?

Hi Ryan,
Thanks for your reply. Now I understood how SSTableLoader works.
- If I understand correctly, the current o.a.c.io.sstable.SSTableLoader
doesn't use LOCAL_ONE or LOCAL_QUORUM. Is it right?
- Is it possible to modify SSTableLoader to allow it access one data
center?
Because
Hi there,
The compaction remains running with our workload.
We are using SATA HDDs RAIDs.
When trying to run cfhistograms on our user_data table, we are getting
this message:

Please see what happens when running some queries on this cf:
C* seems to have more than its share of version x doesn't work, use
