Make pathFinder more efficient about getting orderbooks #11

Closed Reidmcc closed 5 years ago

Reidmcc commented 5 years ago

Describe the solution you'd like Right now pathFinder grabs orderbooks for its calculations separately for each payment path, and this leads to duplicate API calls; if XLM-BTC is in more than one path, pathFinder queries Horizon that pair for each path that contains it.

Requirements

Have pathFinder generate a standalone list of the trading pairs it needs when initialized, idependant of the individual path records
Query each pair once for each cycle and use the query response for all paths that need it

This could be better accomplished with streaming mode: https://www.stellar.org/developers/horizon/reference/streaming.html
