hi,all
I'am using the s3+radosgw, there are some questions confused me very much:
first) An object's size is 400MB, then the whole object will stored
in OSDs as one big single object, but not striped into 4MB objects. so
how can we got workload banlance if we want to store big objects and
small ones?
That is correct, RADOS nor the RADOS gateway stripes objects.
You will get workload balance if you have a (almost) even spread of
workload over your different objects.
The dev's might shed some more light on this.
second) Can we change the number of pgs in a pool that created by S3
clients or just using rados commands?
As far as I know you can't do this through the S3 clients but only with
the rados commands. I also would find it rather weird if you could do
this as a client.
