An extension section of a discovery pattern is a section that allows you to modify or extend the functionality of an existing pattern without customizing it. An extension section can contain shared libraries, which are reusable code snippets that can be invoked from any pattern or extension section. Shared libraries can be used to define common functions, variables, or constants that are used across multiple patterns or extension sections. Shared libraries can also be used to override the default behavior of some built-in functions, such as identification or classification12. References = 1: ITOM: Extending Discovery/Service Mapping Patterns - GlideFast ServiceNow 2: How to Create Discovery Pattern Extensions and Why to Use Them

The mid.discovery.max_pattern_payload_size property defines the maximum overall size for the returned payload that comes from patterns. This property is set on the MID Server and applies to all patterns that run on that MID Server. If the payload size exceeds this limit, the pattern execution fails and an error message is logged in the ECC queue. The default value of this property is 10 MB1.

A horizontal pattern is a type of Discovery pattern that discovers configuration items (CIs) and their relationships by moving across the network from one device to another. A horizontal pattern can use the Change user operation to switch from the default credentials to any other appropriate credentials for a specific device or application. This operation allows the pattern to access different types of CIs with different authentication methods.
