Team Exasol

The holiday season is traditionally a little bit quieter here at Exasol. Still, we had 23 ecosystem releases in December 2021. Here are the most interesting ones for customers.


Performance improvements in the Document Virtual Schemas

File-based data import in Virtual Schemas saw another major performance improvement in version 4.0.0 of the base library. This time in the case you want to import many small files at once. This new feature is available in the S3 Virtual Schema 1.6.0 and later.


CloudWatch Adapter

The CloudWatch Adapter 0.2.0 now supports setting a TLS certificate fingerprint for the connection.


Spark Connector

The same is true for the Spark Connector 1.2.0, which also supports TLS certificate fingerprints now.


Log4J Fixes

In Log4J there were two vulnerabilities in December, CVE-2021-44228, and CVE-2021-45105. We use Log4J only in very few projects and with the exception of one we only use the Log-4J API and not the actual implementation. We nevertheless immediately updated all projects with corresponding dependencies to be on the safe side.
