Hi, I am using Ceph in developer mode. Currently I am implementing Librados examples which are also available in Introduction to Librados section https://docs.ceph.com/docs/master/rados/api/librados-intro/#step-3-creating-.... It says once your app has a cluster handle and a connection to a Ceph Storage Cluster, you may create an I/O Context and begin reading and writing data. For example, *err = rados_write(io, "hw", "Hello World!", 12, 0); if (err < 0) { fprintf(stderr, "%s: Cannot write object \"neo-obj\" to pool %s: %s\n", argv[0], poolname, strerror(-err)); rados_ioctx_destroy(io); rados_shutdown(cluster); exit(1); } else { printf("\nWrote \"Hello World\" to object \"neo-obj\".\n"); }* My question, Is "12" is the number of writes? Because I want to test the with high number of read and writes. Looking for help !
