File metadata over the wire
The data registration utility ligo_register_data requires local copies of files to compute checksums and retrieve file sizes.
Find routines (see gfal2-util
, dmc
, ...) to allow metadata to be retrieved over e.g., gsiftp so that data can be registered in the rucio catalog from locations which don't necessarily host that data. Two obvious use cases:
- Rucio operations on local machines
- Registration operations as a service. E.g., rolling buffer of data transfers without having to run the rucio client at that site.
