**FEATURE REQUEST**
1. Please describe the feature you are requesting.
When using the singleentrylog mode, depending on the throughput, for
example, under the throughput of 200m / s, The default value of the
configuration parameter logsizelimit is 1.2g. At this time, due to the large
throughput, the generation of checkpoint tasks is fast, but the execution time
of checkpoint tasks is long. The speed of the two is inconsistent. A large
number of tasks accumulate in the checkpoint thread, resulting in the
checkpoint bits recorded in the lastmark file greatly lagging behind the
real-time data. Restarting bookie will be abnormally slow. Unnecessary
checkpoint tasks can be eliminated according to the execution time of
checkpoint tasks. The next effective checkpoint task is generated only after
one checkpoint task is executed. The specific way is to clear the accumulated
tasks in the checkpoint thread pool every time a newly generated checkpoint
task is added.
