摘要： Described herein is a technology for providing enhanced transactional caching. In accordance with one aspect, a transactional cache associated with a database is configured. Execution of a write operation on the database is delayed until a flush is determined to be necessary. The write operation is delayed by writing to the transactional cache. The flush is invoked by writing inserted or updated records in the transactional cache to the database via a bulk operation.

摘要： Described herein is a technology for providing enhanced transactional caching. In accordance with one aspect, a transactional cache associated with a database is configured. The enhanced cache may support write operation by partial key or index. Execution of a write operation on the database is delayed until a flush is determined to be necessary. The write operation is delayed by performing the write operation on the transactional cache. The flush is invoked by performing a row-wise bulk operation that updates the database based on the transactional cache.
