"Tested release 5.0"

What do you like best?

In spite of some limitations, the company constantly works on improvements and on new features. The newest version 5.0 demonstrates the company’s desire and ability to compete and to become a leader among the NewSQL vendors.

Unlike the traditional databases that are usually BASE-compliant, VoltDB is a fully ACID-compliant transactional database.

The durability of VoltDB is achieved via ability to update the database schema on the fly, without stopping the database.

The high availability in VoltDB achieved with clustering of the server nodes and data replication across the nodes and clusters.

In summary, the list of strengths:

• It is ACID compliant

• It fits well into a real-time engine category

• Supports a strong management of a failover, high-availability and durability options, and load balancing the workload

• Supports relations as well as JSON data models

What do you dislike?

Since the VoltDB is in-memory database, once the database server stops the data is removed from the memory. That said, the users always need to set such configuration that it will not allow the data loss. VoltDB is not optimized for all types of queries, such as fetching and collating large data sets across multiple tables. VoltDB does not run on Windows and on Unix.

What business problems are you solving with the product? What benefits have you realized?

VoltDB offers a high-throughput, low-latency database operations at a low cost. VoltDB is one of the world's fastest operational databases which allows maximum transaction throughput.

An ability to export live data, that VoltDB provides, can be very useful when business data needs to be passed to other business process. The customers of VoltDB use it mostly for real-time analysis as it demonstrates an excellent performance managing large volumes of transactions in real-time.

"VoltDB is the Leader in Fast Data, Real-time Analytics, and In-memory Databases"

What do you like best?

VoltDB was created from the ground up as an in-memory relational, distributed database. It is not simply one of those Elephants bolting on an in-memory feature to their legacy relational database technology. VoltDB is a true NewSQL database technology.

What do you dislike?

It is a bit pricey compared to other contemporary database technologies. That was an obstacle for us. However; the great team at VoltDB will work with you to get a deal done. Of course, when you see the performance of VoltDB and realize that your other solutions do not compare, you understand what you are paying for.

Recommendations to others considering the product

They offer a good on-line university training program that can get you up to speed on not only the software but it will also increase your understanding of in-memory database technologies and distributed databases.

What business problems are you solving with the product? What benefits have you realized?

We demonstrated in numerous projects that VoltDB could easily provide us with real-time analytics and solve not only our Operational data needs but our IoT and SmartGrid needs when it came to immediate analysis and decision making.

What Relational Databases solution do you use?

Thanks for letting us know!
