The 2-block cache sometimes affects the processing power of bookie. We have encountered the problem of write failure because both caches are full. If the write cache is increased, it will cause too much data in a flush, which will lead to a longer time for a flush, and the cache resources cannot

The current write cache has only 2 blocks, which has the following deficiencies:       1.Insufficient use of cache: When half of the write cache is flushed, it must wait for all the data in the write cache to be flushed before it can be released. With the same write cache size, if we divide the
