Find out what your peers are saying about Snowflake Computing, Oracle, Teradata and others in Data Warehouse."The way that it scales will help a lot of customers that are stuck with Netezza boxes that can't grow any larger."
"The performance is okay as long as the volume of queries is not too high."
"It will be MPP, so performance should improve."
"Exadata's best features are its performance during redo logging and the elasticity of the database handling."
"The new Exadata x9m has an even higher speed of 100GBps connectivity."
"Oracle Exadata's performance is one of its best features. We very satisfied with it."
"Exadata is also a very stable environment. Their Smart Scan feature is great for every banking environment and financial institutions willing to implement it."
"Oracle Exadata is stable."
"What I like best about Oracle Exadata is its good performance. It's also a very fast solution."
"The most valuable feature is that you have the same familiar environment of an Oracle database but with the additional performance you get from this architecture."
"Backup/Restore performance: Fast backups, fast restores (especially useful for creating clone environments)."
"Tech support for dashDB is awful. We usually have tickets open for three to four weeks."
"Ultimately, the product itself has challenges and we are not currently satisfied with the support, either."
"Containers get corrupted very easily. Restoring them using GPFS can result in a lot of issues."
"Right now, we are implementing on ESX VMware 6.0. Support for this platform is poor. Also, one of the backup/recovery options is broken and IBM is not addressing the issue."
"In a future release, I would like to see some upgrade analysis advisors to help with a clear roadmap on steps that need to be taken and some of the automated processes."
"I would like to see more database features and maybe more archiving features, because we need to do data archiving."
"A room for improvement in Oracle Exadata is that it's not very easy to use in a microservices environment. It's not easy to split databases, and if this was easier to do in Oracle Exadata, it would make the solution better. What I'd like to see in the next release of Oracle Exadata is for it to become more modular, so you can use it in a context where the data layer is spread between many independent services."
"Tech support sometimes takes some time to identify and rectify issues."
"License or upgrade management can be difficult and time consuming because it requires login to a separate console."
"The technical support is in need of improvement."
"We have experienced some issues with processing unstructured data on Exadata. This is an important requirement for our AIML based use case. Reactive analytics data can not be prepared easily in Oracle Exadata."
"The setup is a little bit complex. We would like to see the installation part get easier."
