Store Redis scan+scan_info longer than data
This is a proposal to allow to use the scan history a bit more longer than what we have now.
For now, on beamline, and probably depending on the Redis beamline configuration, the scans are not stored more than few minutes.
As result:
- Daiquiri can't display a lot of scans from the history, nor allow to browse the data
- Same for Flint (which is not convenient to compare current scans with previous ones)
- There is no way for now to list the scans from the data files
- The
scan_info
is lost - There is no way for now to reload data without the
scan_info
structure
So my proposal is to tune Redis/BLISS in order to store scan node + scan_info node a bit longer than the data.
This should be enough to
- list the previous scans
- read back the data from files using the
scan_info
stored from Redis
What do you think? @denolf @matias.guijarro @sfisher
