Description
load_vector_index_on_follower specifies whether to automatically load the vector index to memory for follower nodes. This parameter applies to follower nodes in the primary cluster and leader and follower nodes in the standby cluster. If this parameter is set to false, the vector index is not automatically loaded to memory for the specified nodes. Note that this parameter is not synchronized to the standby cluster. In a primary/standby cluster scenario, you must separately set this parameter for the primary and standby clusters.
