Sets the maximum size of models that can be imported. The sum of the size of files specified in the metadata.json file determines the model size. The unit of this parameter is KBytes. The native Vertica model (category=VERTICA_MODELS) is exempted from this limit. If you can export the model from Vertica, and the model is not altered while outside Vertica, you can import it into Vertica again.

The MaxModelSizeKB parameter can be set only by a superuser and only at the database level. It is visible only to a superuser. Its default value is 4GB, and its valid range is between 1KB and 64GB (inclusive).

Examples:

To set this parameter to 3KB:

=> ALTER DATABASE DEFAULT SET MaxModelSizeKB = 3;

To set this parameter to 64GB (the maximum allowed):

=> ALTER DATABASE DEFAULT SET MaxModelSizeKB = 67108864;

To reset this parameter to the default value:

=> ALTER DATABASE DEFAULT CLEAR MaxModelSizeKB;							

Default: 4GB
