[Author’s note: the demo file is a work in progress. Modify it as you see fit.]

Today we’re going to compare various methods one might consider employing to render an arbitrary found set as a JSON object. The demo consists of a table of US customers with 250K records, and the JSON object will be structured like so…

{ 
   State Name: 
      { County : [ [ customer array ] , [ customer array ] ... ] , 
        County : [ [ customer array ] , [ customer array ] ... ] , 
        ...
      } , 
   State Name:  
      { County : [ [ customer array ] , [ customer array ] ... ] , 
        County : [ [ customer array ] , [ customer array ] ... ] , 
        ...
      } , 
   ...
}

…i.e., grouped by state name and county, with customer data represented as a two-dimensional array, for example: Continue reading “Render Found Set as JSON Object” →
