Hello,
I have a mongo database and I sync it with blockchain. To do that, i’m using :
MyContract.getPastEvents("allEvents", { fromBlock: mintBlock, toBlock:lastBlock }, function (error, events) { })
But the problem is, if I ask for like 4000 events, infura node crash (maybe because it’s too big) ?

How to get 4000 past events from a contract without crash ?
