In earlier releases, providing a value for the "enable_chunker" parameter had a negative impact on system performance.

This issue is now resolved. 

The "enable_chunker" parameter is set to "True" resulting in improved system performance.

JDBC complex types return NULL arrays as empty arrays. For example, when executing this SQL statement:

=> SELECT ARRAY[null,ARRAY[1,2,3],null,ARRAY[4,5],null] as array;

The array column the server returns will be:

[[],[1,2,3],[],[4,5],[]]

Because of the null values in the string literal, it should return this value:

[null,[1,2,3],null,[4,5],null]

This is a work around to a limitation in Simba.

The {{install_vertica}} command fails if Transparent Huge Pages (THP) are incorrectly configured. The function that automatically enables THP has been removed. For on-premises installations, follow the steps here [https://docs.vertica.com/24.2.x/en/setup/set-up-on-premises/before-you-install/manually-configured-os-settings/] to manually configure OS settings and disable THP. If THP is not disabled, {{install_vertica}} will return an error.

For installations where THP needs to remain enabled, add the parameter {{--failure-threshold NONE}} when running {{install_vertica}} to bypass this requirement and complete the installation.
