Abstract

See full text

Disclosed are improved methods, systems, and media for cursor sharing and cursor pruning. According to some approaches, existing child cursors are distinguished using a cursor sharing criteria node structure. A sharing criteria node (also referred to as a “diagnostic” node) is created when a sharing criteria mismatch/failure happens. The node contains information about why the child cursor could not be shared and also information that can be used to quickly re-evaluate this sharing criterion in the future.
