Large offline storage with Sencha Touch 2

Question

I am currently working on a mobile application (using Sencha Touch 2 and designed to work on iPad). There is a requirement to pull out a rather large amount of data (3000+ objects, objects of about 30 fields) before the application from the web service, and then save the data locally for offline use. I explored the standard solutions discussed here and elsewhere where localstorage proxies are used to save data after pulling it from the web service, but I run into the terrible QUOTA_EXCEEDED_ERR because of the amount of data I'm trying to save.

There are several threads around discussing things like SQLLite and Lawnchair (including this thread where someone mentions Sencha’s integration with Lawnchair and links to a manual that I can’t find somewhere), but there are no concrete examples or success stories Can anyone recommend a proven method for storing large datasets using Sencha Touch?

EDIT : by asking a similar question on the Sencha forums I am learning how to use SQLite using SQLite Proxy for ST2 . Will update this stream further in the interests of others, as soon as I have time.

Answer 1

Finished with SQLite Proxy for ST2 to solve my problem regarding saving a large dataset. Highly recommended and with a very useful community on Sencha forums that were invaluable in working with the solution.
