Welcome to Staccato's documentation!
The Staccato project provides a service for transferring data (most commonly the data transferred are VM images) from a source end point to a destination end point. Staccato is does not manage or control the storage of that data, it interacts with other services (swift, glance, file systems, etc) which handle that. Staccato's only job is to manage the actual transfer of the data from one storage system to another. Below are a few of the tasks needed to accomplish that job:
- Monitor the progress of a transfer and restart it when needed.
- Negotiate the best possible protocol (for example bittorrent for multicast).
- Manage resource (NIC, disk I/O, etc) and protect them from overheating.
- Verify data integrity and security of the bytes in flight.
Staccato is as a service that does a upload or download of an image on behalf of a client. The client can issue a single, short lived request to move an image. Unlike traditional upload/downloads the client does not have to live for the length of the transfer marshaling the protocol de jour for every single byte. Instead it issues a request and then ends. Later it can check back in with the service to determine progress. Staccato does the work of protocol negotiation and optimal parameter setting, scheduling the transfer, error recovery, and much more.
