Documentation

Definition

The number of database buffer pool flushes is a summary of all the flushing activity resulting from any of the following three conditions.

1) When the number of dirty buffers in a LRU queue reaches its limit determined by LRU_MAX_DIRTY.

2) When the page cleaner threads cant keep up - in other words, a user thread need to acquire a buffer and none are available.

3) Online needs to execute a checkpoint.
