Caching subsys: db, filesystem, do we even need something? #504

Open goodboy opened 1 year ago

goodboy commented 1 year ago

Recently there's been some discussion on a caching layer for stuff like:

MktInfo data that will land in #489
general provider symbology (schemas) and dynamic update of venue instrument offerings
accounting state which is currently entirely managed in TOML files on the local filesystem of the brokerd actor.
aggregated multi-trader order dialog states

maybe more?

FOSS systems worth checking out in this space:

we already are using elasticsearch for some option OI tracking
