4/5

What do you like best about EXASOL?

- Unparalleled query performance: in-memory, massive-parallel processing cluster DB

- Suited for highly analytical workloads

- Comes with the ability to run custom build Python,Lua,R workloads *in database*

- New feature: "Lakehouse Turbo Charge" allows for highly performant queries against Apache Iceberg tables (an open table format) - data is no longer silo'ed in vendor specific systems

What problems is EXASOL solving and how is that benefiting you?

Exasol allows me to run a best-of-breed in my Data Lakehouse architecture and avoid vendor lock-in, by accessing/caching Apache Iceberg tables in my data lake.

It is more cost effective that common competitor clould databases/platforms.

Exasol solves the problem of slow, inefficient data analytics by providing an ultra-fast in-memory database designed for big data workloads eliminating bottlenecks in real-time analytics: Use it for Accelerating certain BI workloads. Even in existing DWH landscapes, you can offload (copy) performance-critical Tables/Data Marts into Exasol, giving you an immediate performance boost without refactoring

The benefits are clear: businesses gain instant access to actionable insights, reducing decision-making cycles from hours to seconds. Scalability ensures performance remains consistent as data grows, while cost efficiency outperforms proprietary alternatives like Oracle. For industries reliant on data-driven strategies (e.g., finance, telecom), Exasol’s speed and flexibility translate directly into competitive advantages, better resource allocation, and faster innovation.

"The fastest database in the world"

4.5/5

What do you like best about EXASOL?

Performance, performance and performance for sure. That's awasome when you can query billion of rows and get results in less than one second. Quite impressive. Review collected by and hosted on G2.com.

What do you dislike about EXASOL?

However, sometimes Exasol optimizer chooses a non-efective way to execute complex queries. But I guess all of the database could have the same issues. Luckily there is some possibilities and tricks to make optimizer creating the better plan and improve performance, e.g. preprocessor. Review collected by and hosted on G2.com.

"A high-performance database for Analytics. Would definitely recommend it."

5/5

What do you like best about EXASOL?

My first experience with Exasol was revealing: when migrating our data warehouse we saw many reports running in 1/10 of the time.

This extraordinary performance allowed to, over time, squeeze much more value from the database, while keeping low maintenance and development costs.

For my Analytics department, migrating to Exasol was the single most important step that we took to provide a better service to business, assure quick development cycles and incur in minimal admin effort. Review collected by and hosted on G2.com.

What do you dislike about EXASOL?

Scripting capabilities can be enhanced and better documented. It is not always easy to find resources capable to program with Lua scripting. Review collected by and hosted on G2.com.

"Exasol Review from a non-profit analytics manager"

5/5

What do you like best about EXASOL?

EXASOL is an incredibly powerful database - its performance mean that I never have to worry about computational efficiency when designing analytics pipelines and can focus on building in complex logic that will allow us to make sure our tool will serve the needs of our field staff.

The EXASOL team has proven to be excellent - both in terms of their willingness to support me queries and their technical knowledge. Review collected by and hosted on G2.com.

What do you dislike about EXASOL?

It is actually to come up with a list of grievances I have with EXASOL - using the database has been an incredible smooth experience from the start. Review collected by and hosted on G2.com.

What problems is EXASOL solving and how is that benefiting you?

EXASOL is the key database technology that sits at the core of our analytics infrastructure. It is the repository for the data collected by our field staff and surgeons, and serves as the data source for all the dashboards built on top of it.

The flexibility and power of the database has allowed us to get more tools out to the field, especially in resource constrained environments where internet signals might be very weak. EXASOL's power has allowed us to reduce one point of failure in the entire system, meaning that we can collect more data about patients, ensure surgeons get paid on time, and that our internal team can always do the crucial data audits and review needed to ensure our programs are delivering a real impact.

"Best choice for on-premise, getting better in the cloud"

4.5/5

What do you like best about EXASOL?

+ Amazing performance in general;

+ Cost-to-performance ratio is very competitive, you'll need much less hardware;

+ Efficient indexed JOINs, probably best in class;

+ Flexible UDF scripts, can be implemented in any programming language and run in parallel; Review collected by and hosted on G2.com.

What do you dislike about EXASOL?

- Lack of native support for composite data types;

- Lack of native partial backup (per-table, per-schema), must use EXPORT instead;

- Detection of data lineage is a bit difficult, unless you implement it yourself externally;

- Cloud capabilities are not fully utilised (yet), but it's not a problem for "on-premise"; Review collected by and hosted on G2.com.
