What do I think about the stability of the solution?

Not more than any new DB – not something particular.

What do I think about the scalability of the solution?

How are customer service and support?

Customer Service:

It's good.

Technical Support:

It's good.

Which solution did I use previously and why did I switch?

I used Oracle Enterprise edition – moving to Greenplum due to the MPP (it’s like Map-Reduce). I prefer a SQL solution rather Hadoop or whatever – especially if you’re moving from RDBMS. Now I’m also using Amazon Redshift from the same reason and also we don’t need to manage any server, it’s only a service and this is our best option especially because we’re already using Amazon.

How was the initial setup?

It's straightforward.

What about the implementation team?

In-house.

What other advice do I have?

Read the documentation and always perform tests.

Session management needs improvement, but performs well with larger data volumes because it uses massively parallel processing.

What is most valuable?

The performance is the most valuable.

How has it helped my organization?

There is only a fraction of performance tuning that you need to be careful about, compared to Oracle DB.

What needs improvement?

Session management for client tools needs work.

For how long have I used the solution?

I've used it for nine months.

How are customer service and technical support?

Customer Service:

Nothing to complain about.

Technical Support:

Nothing to complain about.

Which solution did I use previously and why did I switch?

Previously, there was Oracle database, and the EMC Greenplum database was used for better performance from larger data volumes because it uses massively parallel processing. This increased the performances multiple times while reducing time needed for optimization of database queries.

What about the implementation team?

We had a team from EMC, who had a very high level of expertise.

What other advice do I have?

It's a very good product for reducing the time and man power needed for database optimization for datawarehousing purposes.
