TXN preload by domodwyer · Pull Request #11 · globalsign/mgo (original) (raw)
During 'recurse' loading all of the transactions to be done one-by-one is actually rather expensive. Instead we can load them ahead of time, and even allow the database to load them in whatever order is optimal for the db.
When dealing with some forms of 'setup', the existing preload loads too much data and causes a different O(N^2) behavior. So instead, we cap the number of transactions we will preload, which gives an upper bound on how much we'll over-load.
