Robert Newson commented on COUCHDB-796:
---------------------------------------
Sorry, I pasted a terse summary from #couchdb and was then too busy to flesh
this out.
I'm actually not sure I like the idea of tweaking mochijson2.erl, though it was
suggested (by you iirc ;). Also the notion that numbers magically become
strings at some point feels wrong, but so also does the notion that a sum()
overflows or goes wrong when you hit that limit too.
Rather, I think a guarantee that some bignum.js library is always available and
some prominent docs about it. Ideally a BigDecimal and BigInteger class like
Java has (yes, kill me).

> URL: https://issues.apache.org/jira/browse/COUCHDB-796
> Project: CouchDB
> Issue Type: Improvement
> Components: Database Core
> Affects Versions: 0.11
> Reporter: Robert Newson
> Fix For: 1.0
>
>
> CouchDB uses spidermonkey which can only handle 32 bit integer values before
> overflowing. This might surprise users of map/reduce on large datasets.
> Instead, alter mochijson2.erl to handle bignums and encode numeric values as
> strings.
