Remarks

This event fires once every StatsRefreshInterval to provide the application with the latest cache statistics, as well as information about any in-progress cache operation.

The CacheSize parameter reflects the current size of the cache, in bytes.

The TotalData parameter reflects the total amount of data present in the cache, in bytes.

The UnflushedData parameter reflects the amount of unflushed data present in the cache, in bytes.

The UnflushedFiles parameter reflects the number of unflushed files present in the cache.

The CurrentOperation parameter reflects the cache's current operations; it will be one of the following values:

When CurrentOperation is CACHE_OP_READ or CACHE_OP_WRITE, the CurrentFileId parameter will reflect the Id of the cached file being processed.

Note that this event can fire in the context of any thread.
