Exasol has been widely used by various organizations for a range of use cases. Users have found success with self-service analytics, leveraging the platform's capabilities to gain insights and make data-driven decisions. Additionally, Exasol has proven valuable for ad-hoc queries, allowing users to quickly retrieve specific information on-demand. Financial reporting is another area where the product shines, providing fast, accurate, and timely reports that have resulted in high client satisfaction.

One of the key problems that Exasol addresses is the high cost and poor performance of traditional enterprise data warehouses. By offering an efficient and powerful database technology, Exasol has helped organizations overcome these challenges and streamline their data storage and retrieval processes. Moreover, Exasol serves as a crucial repository for collected data, acting as a central data source for various dashboards and enabling users to monitor and analyze their data effectively.

The flexibility of Exasol has also proven beneficial for resource-constrained environments where internet signals may be weak. Users have been able to deploy more tools on the platform, thanks to its power and adaptability. The multiuser interface of Exasol has facilitated simultaneous data analysis for users and their colleagues, enhancing collaboration capabilities within organizations.

Another significant advantage of Exasol is its ability to improve query performance over Hadoop/Hive. Users have turned to Exasol to address the latency issues associated with these platforms while maintaining fast and efficient data retrieval processes.

In addition to these use cases, organizations in the financial industry rely on Exasol as the backend for reporting and business intelligence. The product replaces Tableau extracts, enabling live connections and true incremental load strategies while centrally managing business logic. This centralized approach ensures efficient data audits and enables timely payments to surgeons.

Overall, the diverse use cases of Exasol highlight its role as a powerful database technology that addresses various challenges in data management, analytics, financial reporting, and more. It offers organizations the flexibility, speed, and reliability needed to make informed decisions and derive meaningful insights from their data.

  2. Absence of native partial backup: Reviewers have pointed out the absence of native partial backup in Exasol, which requires them to use EXPORT instead. This limitation has been raised by several users.

  3. Difficulty in detecting data lineage: Users have expressed difficulties in detecting data lineage within Exasol unless it is implemented externally. This lack of built-in functionality has been highlighted by multiple reviewers.

It used as the reporting and business intelligence backend for our primary financial products.
  • We have found Exasol to be very fast at summarizing large data sets. It has been a great backend for both reporting tools and data analytics/business intelligence. Combined with the fact that data import is also very fast it makes it ideal for a real-time ELT architecture.
  • Exasol is low maintenance. No indexes to maintain (The database auto-manages them) and very little tuning is required.
  • Query processing is optimized for high throughput and high parallelization. This means that even under high loads performance degrades gracefully as opposed to having "pile-ups" and "meltdowns". This has made it a very reliable database for us.
  • Exasol doesn't have some of the advanced enterprise-y features found in some other large corporate database systems (e.g. native row-level and column-level security). However it's pretty customizable (SQL pre-processing, virtual schemas, powerful user-defined-function frameworks) so many of these features can be implemented manually.
Exasol is suited to applications requiring fewer & larger queries (reporting/data analytics/business intelligence tools).

Its per-query overhead makes it unsuitable as an operational database (those are optimized for many & smaller queries.)
  • When we first migrated to Exasol (from a MySQL-backed reporting tool) our clients spent over an order of magnitude less time waiting on reports and since then it has opened up possibilities for reporting and analyzing data that were simply not possible beforehand.
  • SingleStore (formerly MemSQL) and Teradata Vantage Advanced SQL Engine (Teradata Database)
We looked at some others too, but was 5 yrs ago so I don't recall the list. Exasol had the best performance per cost, outstanding performance, and was easy to evaluate. Even their community addition running on my laptop was faster than our existing reporting solution.
I gave it 9/10 instead of 10/10 only because it lacks in a few advanced enterprise features that require manual workarounds. Otherwise our users have had no problem getting up to speed with it (other than SQL syntax issues that are specific to it, but that's true of any DB)
I have had only positive experiences with their support. They are fast, knowledgeable, and courteous. Online support requests get picked up within hours. I've only once had to use their hotline and that was for an emergency. There was even one minor non-security bug report that I reported and which they fixed in the following week's minor release. I was quite impressed.
