Vertica Review

Has improved the majority of our ETL operations, but performance degrades seriously for large datasets

What is our primary use case?

We use this solution as our data warehouse. It handles our analytics and we have power users connected.

How has it helped my organization?

Eighty percent of the ETL operations have improved since implementing this solution. Complex queries are challenging to improve.

What is most valuable?

This most valuable feature is the database designer, which helps significantly improve our storage footprint.

What needs improvement?

There is serious performance degradation for large datasets. Fact-to-fact joins on multi-billion record tables perform poorly. Star schema joins also perform poorly if the fact tables reach more than one billion records and the dimension tables reach more than one million records.

For how long have I used the solution?

Two years.

Which version of this solution are you currently using?

9.0
