Q:

Prevent IndexedDb from growing exponentially in chrome

I wanted to try IndexedDB, to see if it is fit for my purpose.
Doing some testing, I noticed, that its grow rate seems to be exponentially with every insert.
(Only tested in google chrome version 31.0.1650.63 (Offizieller Build 238485) m / Windows by now)
My Code in full: http://pastebin.com/15WK96FY
Basically I save a string with 2.6 mio characters.
Checking window.webkitStorageInfo.queryUsageAndQuota I see that it consumes ~7.8MB, meaning ~3 bytes per character used.
If I save the string 10 times however, I get a usage of ~167MB, meaning ~6.4 bytes per character used.
By saving it 50 times I'm high up in the gigabytes and my computer starts to freeze.
Am I doing something wrong or is there a way around this behaviour?

A:

Your test is wrong. Field test2 should not be indexed.
