Great findings. As you mentioned, unique_ptr and smart_ptr always have a well

Hi Sage and other fellow cephers,
I truly share the pains with you all about filesystem while I am working on
objectstore to improve the performance. As mentioned , there is nothing wrong
with filesystem. Just the Ceph as one of use case need more supports but not

Hi Sage and Somnath,
In my humble opinion, There is another more aggressive solution than raw
block device base keyvalue store as backend for objectstore. The new key value
SSD device with transaction support would be ideal to solve the issues. First
of all, it is raw SSD device. Secondly
be the bottleneck. Anything else in
your mind will be the bottleneck?

Thanks for your feedback. I am trying to get newstore works with rocksdb in

Here are steps I did:

2. sudo ./fio/fio

Hi Varada,
Got a chance to go through the code. Great job. It is much cleaner . Several
questions:
1. What you think about the performance impact with the new implementation?
Such as dynamic library vs static link?
2. Could any vendor just provide a objectstore interfaces complied dynamic
objectstore_aio_open,
.close_file = fio_objectstore_aio_close,
};
Let me know what you think.

James

In the job file src/test/filestore.fio, you can modify

Hi Haomai,
What are you trying to ask is to benchmark local objectstore(like
kvstore/filestore/newstore) locally with FIO(ObjectStore engine)? You want to
purely compare the performance locally for these objectstores, right?
