 **The interconnect module will be preloaded by default as a library.** When the compile option `--disable-preload-ic-module` is turned on, then the interconnect module will not be preloaded, then users need to add `interconnect` into guc `shared_preload_libraries`.

 ## Project Background
 
-UDP2 is a next-generation interconnect protocol implementation based on the original UDP protocol, located in the `contrib/udp2` directory. In CloudBerry Database, the interconnect is responsible for data transmission and synchronization between nodes, serving as a core component for distributed query execution.
+UDP2 is a next-generation interconnect protocol implementation based on the original UDP protocol, located in the `contrib/udp2` directory. In Apache Cloudberry, the interconnect is responsible for data transmission and synchronization between nodes, serving as a core component for distributed query execution.
 
 Currently, the database supports three interconnect protocol implementations:
 - **TCP** (`contrib/interconnect/tcp`) - Reliable transmission based on TCP protocol
