Works on Cassandra database? #124

Open SeungWook-Han opened 8 years ago

SeungWook-Han commented 8 years ago

Hi folks,

Does OLTP Bench work on Cassandra database?

I can't find any documents about using other databases. (cassandra)

I hope to execute OLTP Bench with TPC-C on cassandra.

Can I have any advice?

Does Cassandra have a JDBC driver? If so, then you can try it out and let us know if it works.

You will need to edit this file and add "CASSANDRA" as a supported DatabaseType first:

Cassandra have JDBC driver but it doesn't use SQL. Instead, it uses CQL (Cassandra Query Language). Both are quite similar but not same. I think extra efforts will be needed for use cassandra on OLTP bench like editting read, wirte function in CQL format. Are there any easier way than what I explain above?

Thanks :)

Yes, this is correct. You don't even have to edit the Java code. You can add the Cassandara-specific queries to this file:

Any luck with getting Cassandra integrated with OLTP ? I am having trouble integrating cassandra's jdbc driver with the tool.
