Therefore, about 5,000 of the write operations must have hit the

In other words, who has the vote in a quorum election: all the nodes, or

Transforming every number in a string would entail putting a "flag" on every
number, to tell which one was a genuine number. Something like:
[1.1, 2.2, 3.3, "abc"] ==> [{"_": "1.1"}, {{"_": "2.2"}, {{"_": "3.3"},

mbers of the list, but changing numbers to
integers or multiplying them (essentially the same suggestion) is not an option,
since I have little control over input data, and it will kill performance too (I
deal mainly with geo-spatial data, hence heaps of numbers in arrays of arrays).
Well, t
the past
has shown a few "bignum" libraries for Javascript.
No, storing as string won't do, since I have little contro0l over the content of
documents to be stored... I could write an handler function to transform every
number into a string, but this would sap performance.
