How to avoid heap memory overflow?

Question

JavaScript

I use setInterval, inside which there is a selection from sqlite and a record in mysql. those. copying from database to database. After 20 minutes, the server is interrupted, notifying the heap out of memory. How to avoid it?

setInterval(function () {

   }, 10000);

Answer 1

fetch from sqlite and write to mysql. those. copying from database to database.

make a dump and import, the syntax is the same there. You are doing some crap.
I came up with the problem myself, I heroically try to solve it myself.
