Re: Question about hector api documentation

[Sungju Hong]

Thanks for reply.

I will be engaged in the project using Cassandra soon.

Cassandra version is 1.2.3 and the core service was developed by hector
1.1-3, so I need to be familiar with hector for old code analysis.

I'm considering Datastax java driver for new service.

I appreciate any advice for client library.(environment below)

- Cassandra 1.2.3
- Kafka 0.8.2.2
- RabbitMQ 3.3.5-1

Thanks.

Sungju, Hong

Hi.

Can you please show me the specific error message you are receiving, as
well as the schema for this table (you can use the cql command "describe
table").
