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.

For more information, see the change log.

Enforced security defaults

Auditing is now activated by default in new deployments. New deployments are configured to only accept encrypted connections.

Zone maps

Zone maps is a new feature that allows the database to decrease the I/O and computation cost of certain queries. This feature is also known as partition pruning.

For more information, see Zone maps.

Changed behavior

Python 2 is no longer supported. All Python UDFs should be migrated to Python 3 before updating.
