The project requirements are odd for this one, but I’m looking to get some insight…

I have a CSV file with about 12,000 rows of data, approximately 12-15 columns. I’m converting that to a JSON array and loading it via JSONP (has to run client-side). It takes many seconds to do any kind of querying on the data set to returned a smaller, filtered data set. I’m currently using JLINQ to do the filtering, but I’m essentially just looping through the array and returning a smaller set based on conditions.

Would webdb or indexeddb allow me to do this filtering significantly faster? Any tutorials/articles out there that you know of that tackles this particular type of issue?

    million or more records…
