IndexDB,SQL Lite support in Sencha Touch?

Hi do Sencha Touch already support IndexDB ? Im currently using localStorage and it cant handle large data like 4000+ records for Offline scenario that's why our users is frustrated using my app .

Im looking for other samples out there in using IndexDB and SQLlite using Sencha Touch/ Phonegap but cant find one.

Do you have any suggestions? I read also that in iOS8 localStorage limit is 2.5 MB not like before which is 5MB.

Any help is appreciated.
