Note:

GROUP BY cannot be paired with SQLITE FTS extensions; thus, we perform manual

group checks on the result set in Python before response

Analysis:

The returned JSON structure has been (loosely) optimized for speed on the client

side. Fully forming individual dictionary based responses saves time in
|

Javascript, as the JSON parser is expected to be able to create the objects
|

faster than post-hoc construction in JS. This return structure was compared
|
||||
against returning an array of arrays (all ordered in the same fashion), along with
|
||||
a column list to be associated with each of the result values. While this saves
|
||||
some size on the payload (the same column names don't have to be transmitted for
|
||||
each result), the size of the returned content massively outweighs the
|
||||
predominantly short column names. The only way this structure would be viable is
|

if a significant amount was saved on transfer compared to the slow down in JS
|

object construction; this is (almost) never the case.
