Faster processing and improved memory operations have enhanced transaction and analytics efficiency

The valuable features of Oracle Database In-Memory include its capability to bypass disk storage for faster memory operations, which is critical for transactions and analytics. It also offers specific memory areas, like in-memory cache, that act as intermediaries between disk and buffer cache. This feature helps organizations handle real-time memory requirements effectively.

High-speed data processing, seamless scalability, and excellent high availability making it an optimal choice for those prioritizing performance and efficiency in a database solution

There's a noteworthy consideration when it comes to collecting massive amounts of data. It is not the optimal choice for direct data collection through queries, and it's more suited for aggregation tasks. Attempting to use it for direct extraction, for instance, might lead to memory-related challenges. While MySQL version five might lack extensive SQL capabilities, SingleStore also has its constraints, requiring simpler SQL writing. This becomes evident when seeking advanced functionalities like window functions or JSON functions, where SingleStore doesn't offer an extensive toolkit, necessitating a more straightforward approach to SQL.

Quotes from Members

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

Pros

"The solution's most valuable feature is its performance optimization within our hardware environment."

"The application development is very user-friendly."

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

"It accelerates query processing, which in turn speeds up operations and streamlines workflow, and ultimately enhancing productivity."

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

"The on-premise version is stable. We have different teams and resources for the server side, for admin, and for development. We can easily take care of all the services and applications."

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

"The product offers high scalability."

More Oracle Database In-Memory pros

"The paramount advantage is the exceptional speed."

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

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

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

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

"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

"Technical support is below our expectations currently. It could be improved."

"They should improve the solution's scalability for large databases."

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

"I would like Oracle Database In-Memory to include a data replication feature."

"The dashboard requires some refreshment or configuration improvements."

"We use some partitions in In-Memory. We have a very large table and a low dose. It is very expensive in data to load all of them into In-Memory. It takes up more memory slots in the server, as well as a lot of RAM. We use last partitions on the table. We always need to create a script and make a schedule that can load a last partition in In-Memory. Oracle doesn't have features to do this automatically. I would like them to allow us to load last partitions, as well as other table partitions, in In-Memory. I think a good feature would do that automatically, letting you see a table, load a large partition, and monitor loading memory. It's quite a good feature."

"The product could be more economical."

"The high cost of the product is an area of concern where improvements are required."

More Oracle Database In-Memory cons

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

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

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

"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."

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

Pricing and Cost Advice

"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."

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

"The solution's pricing is high."

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

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

"The product is expensive."

"Oracle Database In-Memory is expensive."

"Database In-Memory is priced a bit higher than its competitors like Microsoft."

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."

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

"SingleStore is a bit expensive."

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

"Using it for analytical purposes can be cost-effective in the long run, especially in terms of infrastructure."
