> Test case:
> I created two queues test_1 and test_2. 
> From the same time send message to test_1 and test_2 queues,the message size is 10k,
but send to test_1 is fast, send to test_2 is slow, the aim is allow each leveldb file contains
a large number of test_1's messages and a small amount of test_2's messages.
> after stop send, test_1 stored 686 messages,test_1 stored 141888 messages, generated
following leveldb of files :
> 101M    0000000000000000.log
> 101M    000000000640077d.log
> 101M    000000000c800a63.log
> 101M    0000000012c00eeb.log
> 101M    0000000019001432.log
> 7.1M    000000001f4017fe.index
> 30M     000000001f4017fe.log
> After have consumed test_1 of all messages. But leveled of files are't change, file capacity
is not reduced.This will lead to store a small amount  of messages take up a lot of disk capacity.
> The how to solve this problem? 
> Thanks.
