How to fix Long Method Complexity

/**
 * This class does a full resync of the database by
 * enqueuing an outbound action for every single object
 * that we care about.
 *
 * This class, and its related class Jetpack_Sync_Module, contain a few non-obvious optimisations that should be explained:
 * - we fire an action called jetpack_full_sync_start so that WPCOM can erase the contents of the cached database
 * - for each object type, we page through the object IDs and enqueue them by firing some monitored actions
 * - we load the full objects for those IDs in chunks of Jetpack_Sync_Module::ARRAY_CHUNK_SIZE (to reduce the number of MySQL calls)
 * - we fire a trigger for the entire array which the Jetpack_Sync_Listener then serializes and queues.
