• who: Ole, Antons, Matteo, Ashley, Mark, AndreM
• what:
  • SP1 database backend
  • MongoDB seems to match our requirements better than redis
  • other NoSQL DBs possibly also good -- but we neither have time nor energy for a big shootout
  • important features (compared to redis)
    • efficient searches / query filters (on values, such as session IDs)
    • JSON
    • pub/sub
    • bulk ops
    • can do atomic ops / transactions (not always trivial, but always possible)
    • ssl connection
  • seems very sufficient for SP1
  • TODO Ole: simple performance check (create 1k small docs over high-latency link, etc). Compare to redis as baseline. Agree to use MongoDB baseline perf is in same ballpark.
  • TODO Ole: define type of MongoDB entries we need (probably approx 1 per stateful entity? Check if that makes sense), and define who owns those entries in what state. We can probably leave remainder of the data model fluid for a while
