pscache

A "live" hub for intermediate LCLS analysis results. Useful for cases where the analysis is too complex for AMI and ~2-3 min delay is acceptable. Emphasizes simple and flexible access to data.

Schema

Each experiment will recieve it's own REDIS DB. Within that DB, there will be the following key:value pairs

key value type contents meta/data

---

• run(#):keyinfo hash list of keys metadata
• run#:(key) list data data

This way the user can:

1. Query what runs are avaliable ("run*:keyinfo")
2. Query what keys are avaliable for that run ("run(#):keyinfo")
3. Get the data for a specific key ("run#:(key)")

to do

1. test performance
2. to xarray
3. (for later) one DB per expt
