   @hililiwei Partition field data is discrete when read snapshot phase. I 
write a defective code when use LRU map. Beacause I don't close writer. Thanks 
for your suggestion. I add memory to avoid oom but checkpoint time is too long. 
I think cost many time to close writer. I increase checkpoint interval to avoid 
frequently close writer. Do you have any suggestion?
