Room For Improvement

IBM Db2 requires improved interfaces, integration, and performance, with focus on scalability, usability, security, and cost-effective solutions.

SingleStore needs improvements in data distribution, SQL features, documentation, integration, error handling, administration, monitoring, migration, and community support.

Understanding the basic structure of the database, how logs or log shipping happens, how clustering works, how logs are written, where all information is stored, and how it needs to be taken care of are all critical pieces of information.

It might be slightly slower than other database vendors, but it works well since banks typically do not move quickly with leading-edge technology.

Associate Director, Data Architecture at a financial services firm with 10,001+ employees

Error handling needs attention. When it fails due to memory, it only indicates that but not exactly in which process it failed.

Senior Software Engineer at Honeywell

The data which is sent to DataDog sometimes does not match with the SingleStore dashboard.

reviewer2796066

Devops Engineer at a tech vendor with 51-200 employees

Better documentation for advanced use cases, especially where data volumes are very high and queries are frequent, would help us manage the feature more efficiently.

Database has secured high-volume transactions and supports fast, compliant workflow processing

Founder, Director at perfTech Solutions Pvt Ltd

Sterling B2B Integrator is a highly transactional-oriented application, which can be described as an OLTP application. Any data that flows through the application is stored in the database for each step that it performs. IBM Db2 Database helps the application work much faster from an OLTP perspective. IBM Db2 Database is SSL enabled, which means that from the security point of view, any access to the database is through SSL. Additionally, all compliance-related aspects have been taken care of from the database point of view, including database encryption and security-related features. It is highly scalable, and its performance related to database pruning is very good. It can be scaled vertically or horizontally so that data insertions and data access are much faster and more secure compared to how Oracle or other databases work.

Real-time analytics has transformed daily decisions and delivers fast dashboards from streaming data

Senior Software Engineer at Honeywell

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.
