A simple demonstration of LIBRADOS binding to RADOS cluster

radospybinddemo.py

### Import of the Python Rados library classes
### https://github.com/ceph/ceph/blob/master/src/pybind/rados.py
from rados import Rados,ObjectIterator

### Initialize Rados class
cluster = Rados()
### /etc/ceph/ceph.conf file is read
cluster.conf_read_file()
print "Configuration file successfully loaded [OK]"
### Connection to the RADOS cluster
cluster.connect()
print "Connection to cluster initialised [OK]"
### Returns an array of the pools present in RADOS

print "The pools present in rados cluster are: \n", cluster.list_pools()

###  Here I create a pool
cluster.create_pool("mypool")
### Opens a IO context
mypool = cluster.open_ioctx("mypool")
### I create data
data = 'mydata' * 10
### Object myobject is created with "My data" in it
mypool.write('myobject', data)
### data is outputed out of the RADOS cluster
print mypool.read('myobject')

### The pool is deleted
cluster.delete_pool("mypool")

### I close the IO context and the connection to RADOS
mypool.close()
cluster.shutdown()
