SingleStore needs improvements in data distribution, SQL features, documentation, integration, error handling, administration, monitoring, migration, and community support.
Enhancing features like CAG augmentation and cache augmentation could significantly optimize performance for large language models.

The area where improvement is required the most in the product is the UI.
Technical Solution Architect at Vodafone
The data which is sent to DataDog sometimes does not match with the SingleStore dashboard.

I would appreciate out-of-the-box integrations with commonly used data ecosystem tools and built-in monitoring and observability capabilities for SingleStore.

Setup Cost

Oracle Database In-Memory is costly, yet offers valuable performance and features, benefiting larger enterprises despite high licensing fees.
SingleStore offers transparent pricing with cloud and on-premises options, though costs vary; free trials are available for exploration.
Recent reductions in cloud costs and learning opportunities, such as free portals for students, make the pricing reasonable without hindering access to powerful features and performance.
DB Architect / Consultant at Virtusa Global
The pricing for Oracle Database In-Memory is more affordable.
Sr. Oracle Database Administrator at Shoukat Khanum Memorial Hospital
My experience with pricing, setup cost, and licensing is that it can be a bit expensive for startups.

Valuable Features

Oracle Database In-Memory enhances performance with real-time analytics, backward compatibility, automated configuration, fast queries, and efficient management.
SingleStore offers fast, scalable data handling with resilience, supporting complex operations and improving productivity through integration and ease of use.
The biggest benefit of Oracle Database In-Memory is dealing with a huge amount of information without any latency for our response time.
Technical Solution Architect at Vodafone
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.
DB Architect / Consultant at Virtusa Global
SingleStore is a distributed database that has the advantage that at any moment when resources are insufficient, there is a possibility to add more nodes, and everything is added online.

Hosney Osman - PeerSpot reviewer
Technical Solution Architect at Vodafone
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.
Kelvin  Ben - PeerSpot reviewer
Senior Software Engineer at Honeywell
Real-time analytics has transformed daily decisions and delivers fast dashboards from streaming data
The best features SingleStore offers include fast data recovery and data compression by 80 percent. Having the information in sheets helps me to process the information quickly. Simplicity in T-SQL is another aspect I appreciate. Data recovery and sheet-based processing help my team on a day-to-day basis by enabling us to handle information efficiently. I would like to add that the data compression by 80 percent helps us in an excellent way since we are very fast in obtaining the data for our dashboards and the compression of the information is great. SingleStore has impacted my organization positively by enabling us to run low-latency analytics and model-driven use cases at scale, which is quite difficult for OLAP and OLTP databases alone. It has been very helpful because our internal clients are happy to have the data and make data-driven decisions easily. Making decisions based on data within a two-hour delay to the transactional database is excellent since we went from twenty-four hours to two hours. I think the best contribution is decision-making with data that is close to reality. Reducing that delay from twenty-four hours to two hours has significantly affected my team and business outcomes by increasing productivity. We have been able to serve all our customers, and they are very happy. We can deliver to them on time.
