Constants

const BatchUpdateSQLSize = 10000
View Source 
const IteratorPrefetchSize = 1000

IteratorPrefetchSize is the amount of records to maybeFetch from PG

View Source 
const MaxBatchDelay = time.Millisecond * 3

MaxBatchDelay - 3ms was chosen as a max delay time for critical path queries. It trades off amount of queries per second (and thus effectiveness of the batching mechanism) with added latency. Since reducing # of expensive operations is only beneficial when there are a lot of concurrent requests, 

the sweet spot is probably between 1-5 milliseconds (representing 200-1000 requests/second to the data store).

3ms of delay with ~300 requests/second per resource sounds like a reasonable tradeoff.
