This disclosure provides methods and techniques of data replication involving cross replication group (RG) references. The present disclosure avoids automatic replication failing when an entity in an RG refers to another entity external to the RG. The entity to be replicated within the RG is referred to as the “referring entity,” and the entity as the dangling reference is referred to as the “referred entity.” Although the referring and referred entities are not replicated together in a replication operation, the referred entity may have already been replicated to the target account in another replication operation on a different replication group. In such cases, the data replication procedure may, according to aspects of the present disclosure, check if the referred entity has already been replicated, and if so, proceed to replicate the referring entity without fail, and link the referring and referred entities to enable normal functioning of the referring entity.

This invention discloses a built-in hinge for a high-load-bearing, high-safety outward-opening window and a method for installing the window sash. The built-in hinge includes a slide rail, a slider, a long rod, a middle rod, a short rod, and a support arm. One end of the long rod is hinged to the slide rail, and one end of the middle rod and one end of the short rod are slidably connected to the slide rail. The middle rod and the short rod are cross-hinged. The other end of the middle rod is connected to the long rod, and the other ends of the short rod and the long rod are connected to the support arm. The hinge points A and B between the middle rod and the long and short rods, and the hinge points C and D between the support arm and the short and long rods, form a quadrilateral ABCD. The connection point on the support arm that fixes the window sash is eccentrically inward towards the line connecting the hinge points CD. During the opening and closing process of the hinge of this invention, the gap between the frame and sash profiles is reduced from the conventional 7mm or more to 4mm, preventing collision between the window sash profile and the window frame profile. This shortens the distance between the two profiles, improving the aesthetics of the window while also enhancing the overall thermal insulation, sealing, and safety of the window.
