hi, all:
Currently at keyvaluestore, osd send sync
request(submit_transaction_sync) to filestore when it finishes a
transaction. But sata disk is not suitable for doing sync request. ssd
disk is more suitable.
So I think whether we could separate leveldb *.log file with *.sst
file and move *.log to ssd
disk, which is similar with journal file in ceph.
But now, the original leveldb do not support to separate log file
and sst file.
Wait for your comment.
Thanks.
