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

---

• runs set list of runs metadata
• run(#):keys hash key:"shape-type" metadata
• run#:(key) list list of data data

This way the user can:

1. Query what runs are avaliable ("runs")
2. Query what keys are avaliable for that run ("run(#):keys")
3. Get the expected shape and type for a key ("run(#):keys" "key")
4. Get the data for a specific key ("run#:(key)")

to do

1a. data lifetime 1b. run length 2. to xarray 3. (for later) one DB per expt
