i am using Startio Cassandra it way better than stargate as it works on the
latest release of Cassandra and is better on my performance.
we are using it for fulltext search use case

attached is the code . You follow the process for compiling and using the
code.
If anything more is required please let me know. The Jar file has to be put
into /usr/share/cassandra/conf/triggers.
Hope this helps

My group is seeing the same thing and also can not figure out why its
happening.

I did figure this out:
When adding a columnfamily, the query timed out before all nodes replied,
and I sent the schema out again. Half the nodes ended up with the CF
having UUID A and half the nodes ended up with the new CF but UUID B.
UnknownColumnFamilyExceptions were thrown until the enqueued
Yes Asit you can share it with me, let c if we can implement with our
requirement.

Duncan: I'm thinking it might be something like that. I'm also seeing just
a ton of garbage collection on the box, could it be pulling rows for all
100k attrs for a given row_time into memory since only row_time is the
partition key?

Also, two control questions:
- Are you using EBS for data storage? It might introduce additional
latencies.
- Are you doing proper paging when querying the keyspace?

Sure. I updated the YCSB code to pass a client ID as input parameter and
then stored the clientID in the properties and used it in the DBWrapper
class for logging per operation

Hi,
I'm working on a system which has to deal with time series data. I've been
happy using Cassandra for time series and Spark looks promising as a
computational platform.
I consider chunking time series in Cassandra necessary, e.g. by 3 weeks as
kairosdb does it. This allows an 8 byte chunk
Hi Rahul,
i have created a trigger which inserts a default value into the table. But
everyone are against using it. As its an external code which may be
uncompatible in future releases. Its was a chnallenge as all the examples
are of old 2.0.X veresion where RowMutable package is used which is
Compacted partition maximum bytes: 36904729268
thats huge... 36gb rows are gonna cause a lot of problems, even when you
specify a precise cell under this it still is going to have an enormous
column index to deserialize on every read for the partition. As mentioned
above, you should include

Hi,
I checked Startio Cassandra but couldn't get any good documentation for the
same.
Can you give me some pointers on how to use it.
Do I have to build it from the source or I can use it directly with jar
files as in case of Stargate.
Since I was looking for solution which I don't need a full

For the record, it is my understanding that you almost certainly should not
use the current Cassandra triggers

This seems
Enable tracing in cqlsh and see how many sstables are being lifted to
satisfy the query (are you repeatedly writing to the same partition
[row_time]) over time?).
Also watch for whether you're hitting a lot of tombstones (are you deleting
lots of values in the same partition over time?).

Hi,
You can download Stratio Cassandra binaries from
https://s3.amazonaws.com/stratioorg/cassandra/stratio-cassandra-2.1.3.1-bin.tar.gz
You can get info about how to build and getting started at its README file
https://github.com/Stratio/stratio-cassandra/blob/master/README.md. More
detailed
nodetool cfhistograms is also very helpful in diagnosing these kinds of
data modelling issues.

Hey guys,
We're having a very strange issue: deleted columns get resurrected when
repair is run on a node.
Info about the setup. Cassandra 2.0.13, multi datacenter with 12 nodes in
one datacenter and 6 nodes in another one. Schema:
