space), thus saving time in future recovery. Lazy writer makes better use of the buffer pool. It regularly checks the data cache, writes unused dirty pages to the disk according to the LRU algorithm, and clears dirty pages to release memory space. The Eager writer exists for batch inserts such as BCP. This process writes dirty data pages associated with non-log operations (such as large-capacity insertion and selection of insertion. This process allo
