ABSTRACT:
Various embodiments of the present invention are directed to synchronization utilizing one or more optimizations through the utilization of metadata. For several embodiments of the present invention, one method for optimizing synchronization is to reduce the overhead required for said synchronization by having each peer only tracking changes for itself and other peers within its change community (or communities) (a.k.a., “Intra-Community-Only Change Tracking Optimization”). For certain embodiments of the present invention, another method for optimizing synchronization is to not create synchronization overhead until required. For numerous embodiments of the present invention, yet another method for optimizing synchronization is to minimize redundant use of a partner's unique global ID—a large and cumbersome number—and to instead maintain a table that cross-references each partner (and its unique global ID) with a smaller and much less cumbersome partner key.
