Main features
-
Separation of OS and software

Exasol no longer includes an operating system, but is instead provided as a software package that can be deployed on a public cloud platform or installed on a Linux system on your own hardware.
For more information, see What’s New in Exasol?.
-
Decoupling of storage and compute
-
For native cloud deployments on AWS, persistent storage is moved from local discs to object storage, such as AWS S3. This architecture also enables multi-cluster support.
For more information, see Storage Management.
-
Multi-cluster support in cloud deployments
-
For native cloud deployments on AWS, a database now supports multiple compute clusters operating on the same data. This enables you to split workloads on demand.
For more information, see Database Management.
-
TLS 1.3
-
TLS support is extended to TLS 1.3 and supports specifying a list of allowed ciphers.
For more information, see the change log.

New join order optimizer
-
The new join order optimizer, which was previously a preview feature, is now activated by default.

-
Enforced security defaults
-
Auditing is now activated by default in new deployments. New deployments are configured to only accept encrypted connections.
-
Zone maps
-

For more information, see Zone maps.
