OverviewDocs:http://docs.ceph.com/docsCeph is a distributed file system that adds replication and fault tolerance while maintaining POSIX compatibility. The most characteristic of Ceph is the distributed meta-data server, which distributes the file location by crush (controlled Replication under scalable Hashing) this quasi-algorithm. The core of Ceph is the Rados (reliableautonomic distributed Object Store), an object cluster store, which itself provides high availability, error detection, and

What I want is access/opt/virtual.fileIs equivalent to dynamically merging these three files into one as one for access.
This requirement is not a request to merge js/css in nginx_http_concat.
This is because files are separated by 5 MB/block to ensure stability during File Uploading. although these blocks can also be merged using programs, there is no software for the system to make virtual files, point to these parts, so you don't need to merge them.
This must be achieved using
Because when uploading the file in order to ensure stability, according to the case of 5m/block upload, although you can also use the program to merge these blocks, but there is no software can let the system do virtual files, point to these tiles, so you can not merge

Circuit BreakerThe circuit breaker model originates from Martin Fowler's circuit breaker. "Circuit Breaker" itself is a switch device, used in the circuit to protect the line overload, when the circuit has a short circuit, "circuit breaker" can timely cut off the fault circuit, to prevent the occurrence of overload, heat, and even fire serious consequences.In a distributed architecture, the role of the circuit breaker pattern is similar, when a service unit fails (similar to a short-circuit with
