Overall Satisfaction with Exasol
We use Exasol as the main databaseplatform for Data Warehouse / BI and all ELT processes. We transitioned from MS SQL server in 2018 to Exasol, because of huge performance problems. Exasol solved these issues and going from 2-3 days between new data, we are now able to have daily updates in the big fact tables and dimensions, but also intraday updating every 5 minutes from +100 end points. Ad-hoc reporting that sometimes stalled the system is now running in minuttes. All the ETL/ELT processes is much faster than before and we have 10 times more users on the system than before on a small cluster.
Pros
- Performance in ELT/ETL transformations
- Analytical queries for ad-hoc reporting
- Python and java code directly in the database near the data!
Cons
- Better backup possibilities
- Better management tool like the exaplus
- Public sector, so it does not influence ROI, but it has answered a lot of political questions that was not able to be answered earlier in time.
Exasol have the best performance by far in analytical queries (DW/BI). Compared to the other database we use much less time on maintenance, actually almost 0 time on indexes distributing data on nodes etc. The system just works out-of-box as long as you have memory enough.
