Hey Jonathan,
Thanks for your reply.
i created schema structure in this manner
CREATE SCHEMA schemaname WITH replication = { 'class' : 'SimpleStrategy',
'replication_factor' : 1 };
and table according to requirement.
I didn't used node structure.
So will it be the reason for performance?
And c
Hi all,
I notice that descanter 1.1.1doesn’t support User defined types (as far as I
can see). Is it just a matter of importing a template or will we need to wait
for full 2.1 support in descanter ?

Hi Andrew,
DevCenter has a complete CQL parser inside which helps with the offline
validations and suggestions. So the bad news is that it requires a new
version for every CQL grammar change.
The good news is that this wait is not going to be too long (I cannot talk
yet about a specific release da
Hi, All,
I use the following configuration (in yaml file) to enable the client-to-node

keystore: path-to-keystore-file
keystore_password: some-password
truststore: path-to-truststore-file

I’m not sure I understand correctly “for example column.name would be
event_name("temperature")“, what I gather however is that you have multiple
events that may or may not have certain properties, in your example I
believe you mean you want a CF for events with a type event_name that

I am fairly new to Cassandra. We have a 9 node cluster, 5 in one DC and 4 in
another.
Running a repair on a large column family seems to be moving much slower than I
expect.
Looking at nodetool compaction stats it indicates the Validation phase is
running that the total bytes is 4.5T (45053362
Are you using Cassandra 2.0 & vnodes? If so, repair takes forever.
This problem is addressed in 2.1.

With a 4.5 TB table and just 4 nodes, repair will likely take forever for
any version.

I am on DSE 4.0.3 which is 2.0.7.
If 4.5.1 is NOT 2.1. I guess an upgrade will not buy me much…..
The bad thing is that table is not our largest….. :(

If you're using DSE you might want to contact Datastax support, rather
than the ML.

Well, in that case, you may want to roll your own script for doing
constant repairs of your cluster, and extend your gc grace seconds so
you can repair the whole cluster before the tombstones are cleared.

I have the requirements to periodically run full tables scans on our data.
It’s mostly for repair tasks or making bulk UPDATEs… but I’d prefer to do
it in Java because I need something mildly trivial.
Pig / hadoop / etc are mildly overkill for this. I don’t want or need a

What SSD was it? There are a lot of variability in terms of SSD
performance.
1. Is it a new vs old SSD? Old SSDs can become slower if they’re really
worn out
2. was the office SSD near capacity holding other data?
3. what models were they?
SSD != SSD… there is a massive amount of performan
