/**
* Annotates the field or getter of an {@link Entity} property, to indicate that it will not be
* mapped to any column (neither during reads nor writes).
*
* Example:
*
*
* @Transient private int notAColumn;
*
*
* This information is used by the mapper processor to exclude the property from generated queries.
*
* Please note that {@code Transient} takes precedence over {@link PartitionKey} and {@link
