Real-time analytics have transformed response times and support huge data volumes with compression

I do not have any comment related to the improvement of the solution; for sure, it needs improvement, but for my use cases, it is very sufficient, and I think for the biggest companies, it needs a very powerful infrastructure. The area where improvement is required the most in the product is the UI. The problem with the UI is that it is not complex for understanding, but it needs some training to know what each button does, how it works, and the many variables needed.

An excellent choice for diverse data processing needs with exceptional in-memory capabilities, robust failover mechanisms, easy scalability and high performance

Scalability is its key strength. Adding servers for scalability is a straightforward process involving simply incorporating a few additional servers and recycling the cluster triggers automatic repartitioning and redistribution of data. For instance, if the initial database creation involved a hundred servers and later, four more servers are added, specific commands can be executed to increase the partitions to one hundred twenty. The data is then efficiently redistributed across the expanded partitions without the need for manual data movement, ensuring a seamless and efficient scalability process. In my current organization, approximately three projects involve the usage of SingleStore, with a team size ranging from ten to twenty individuals.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"We find the dashboard and the speed of data processing very valuable in Oracle Database In-Memory."

"It efficiently handles low-code data and supports read-and-write operations for clustering."

"I like Oracle because it is a backward-compatible solution."

"The benefits of data compression in Oracle Database In-Memory are great because we are using data, and it saves a lot regarding sizing."

"The most valuable aspects of this solution are the fast caching and improved performance to the database"

"We can integrate it with any data sources as well."

"Oracle Database In-Memory is a suite of features that improves performance for real-time analytics and mixed workloads."

"The most valuable feature is that Database-In-Memory is more consistent and faster than traditional databases as it requires fewer CPUs to process instructions."

More Oracle Database In-Memory pros

"The product can automatically reinstall and reconfigure in case of a shutdown."

"The ability to store data in memory is a standout feature, enhanced by robust failover mechanisms."

"The paramount advantage is the exceptional speed."

"MemSQL supports the MySQL protocol, and many functions are similar, so the learning curve is very short."

"The most valuable feature is the ability to create pipelines, streamline and extract data from the pipelines."

"It's a distributed relational database, so it does not have a single server, it has multiple servers. Its architecture itself is fast because it has multiple nodes to distribute the workload and process large amounts of data."

Cons

"It would be good if Oracle could reduce downtime when transferring from non-In-Memory to In-Memory."

"The pricing could be improved. It would ideal if it was more reasonable."

"Lacks sufficient integration with other tools."

"They should lower the price. My customers think that it's too expensive."

"The query optimization and backup features should be added."

"The solution is quite expensive."

"The area where improvement is required the most in the product is the UI."

"The solution should move to the new way of writing software code with AI that is intelligent and learns."

More Oracle Database In-Memory cons

"Having the ability to migrate servers using a single command would be extremely beneficial."

"There should be more pipelines available because I think that if MemSQL can connect to other services, that would be great."

"For new customers, it's very tough to start. Their documentation isn't organized, and there's no online training available. SingleStore is working on it, but that's a major drawback."

"We don't get good discounts in Pakistan."

"Poor key distribution can significantly impact performance, requiring a backward approach in design rather than adding tables incrementally."

"It is not the optimal choice for direct data collection through queries, and it's more suited for aggregation tasks."

Pricing and Cost Advice

"Oracle Database In-Memory is expensive."

"It's quite costly and it comes with a fixed price."

"The pricing is pretty good so I rate it an eight out of ten."

"The platform's licensing cost needs improvement."

"There is a need to make a yearly payment towards the licensing costs, after which there is any to pay towards the support cost attached to the solution."

"I rate the pricing a zero out of ten because Database In-Memory is too costly."

"The solution's pricing is high."

More Oracle Database In-Memory pricing and cost advice

"They have two main options: cloud installation and bare-metal installation, each with different pricing models."

"I would advise users to try the free 128GB version."

"The product's licensing is not expensive. It is comparable."
