v.19.1Improvements

Added Low_cardinality_allow_in_native_format Setting

Added low_cardinality_allow_in_native_format setting. If disabled, do not use LowCadrinality type in Native format. #3879 (KochetovNicolai)
Added the low_cardinality_allow_in_native_format setting to control the use of LowCardinality data types in the Native format.

Why it matters

This feature allows users to disable the use of LowCardinality type in the Native format. It solves potential compatibility or implementation issues when working with Native format serialization involving LowCardinality types, giving users more control over data format behaviors.

How to use it

Set the low_cardinality_allow_in_native_format setting to false to prevent the LowCardinality type from being used in the Native format. This can be done by specifying the setting in your query or server configuration.
