I'd like to investigate using Counters in hadoop using
ColumnFamilyOutputFormat.
But i see that this class uses outdated ..hadoop.arvo classes
Does it make sense to use counters for hadoop output?
If i try rewriting ColumnFamilyOutputFormat and friends should it be to
the normal ..avro classes,
Just checked. Seems to be present in CF on all nodes (in both
datacenters), but are not indexed correctly
On each node I've used sstablekeys for all CF_NAME-f-XX-Data.db files.
In cassandra-cli I've (using node that behaves correctly) made query
get CF_NAME where foo = bar, got correct number of r

Hi,
Additionally please take a look at Kundera.
Kundera is an open source and currently supporting ORM over CASSANDRA, Hbase,
MongoDB.
Support for REDIS will be there in future.

Hi,
I think IN clause for SELECT and UPDATE will be supported in v0.8.1.
See https://issues.apache.org/jira/browse/CASSANDRA-2553

I have some severe problems on our production site.
I created the following test program to reproduce the issue with Cassandra
0.7.6 (with empty data set).
I use the following data-model

column_type: Super
gc_grace_seconds: 60

Avro is there because (1) a long time ago (it now seems) we thought we
were going to move the main RPC layer to Avro and (2) it simplifies
using Avro for Streaming, which also seems misguided now
(https://issues.apache.org/jira/browse/CASSANDRA-1497).
Using "native" Thrift mutations makes the most
Would you have a simple script to reproduce the issue ?
And could you open a JIRA ticket.

FWIW, as I mentioned in the 1497 comments, the patch makes it abstract so that
you can have any rpc/marshalling format you want with a simple extension point.
So if we want to move to something besides avro, or even like I mentioned do
something with Dumbo for streaming, it's easy to extend.

You need to use CQL.

You need to design your schema carefully as your application needs.

Thank you Narendra/Aaron. Sorry for late respponse. PFB further information

1) How do you delete the data in the cli ? Is it a row delete e.g. del
MyCF['my-key'];

2) What client are you using the insert the row the second time ? e.g.
