The best article again! Do you know when will you come up with the third post providing several hands-on examples for Cassandra with Java? I am really looking forward to the third one as I may have to use it in my project soon.

Hmm, hard to say. Cassandra may not be the silver bullet. Simple Reads/Writes are generally faster than on any comparable Sql database, but complicated queries need to be rewritten in your application logic, especially of you use higher order functions such as joins, grouping, sorting, etc.. And there is no tool that translates SQL queries to the according logic code. So you have to ponder each SQL query whether it easy to be migrated to cassandra.

Hi,

I have a requirement of using Cassandra in my application. In my application there is one table with lot of data and most of my application uses that table. Due to lot of data,performance of the application is decreasing when i use that table is in Oracle.

So, I have decided to use the Cassandra database for that one table and all other tables in oracle. Lot of business logic is dependent on that table.

No my question is, Can I use the Cassandra for a table which has lot of business logic.

I am unable to implement lot of where clauses for Cassandra database.

Is there any supporting tool to use Cassandra in an efficient way?

Please let me know…
i am in urgency..

Thanks in advance

Worked like a charm on Vista 32bit. Thank you!
I just added 2 lines in cassandra.bat to set my env variables:
set JAVA_HOME=C:\Program Files\Java\jre6
set CASSANDRA_HOME=c:\sand\cassandra
