I read few articles about IndexdDB, but couldn\'t find details about the lifetime of persisted data. I plan to use it for a session of data manipulation and upload once the
IndexedDB data belong to a type of temporary. So these data can be wiped out at any time.
These data size/lifetime are managed by very new Quota Management API.
In the future, IndexedDB could possibly used persistance type (not likely and not good idea too).
