= How to add extra parameters =

 * add the new parameter definition to the CouchDB document with the ID itemlist.
 * add the new parameter to the view definition of get_all_data

= Note =

=== Resample work ===

Resample works, but very very slow. Why? Because it is querying each data row per http request, for a aggregation with wide interval, this should not be a problem, but as the interval gets smaller, it will be very slow. 

Solution: Requires a mapreduce function to do aggregation

Status: Pending

=== Data Query Speed ===

Currently the speed of caching is roughly 250kB/s on localhost. Pretty slow. Current approach uses a buffer to request 10 thousand data rows per http request. I feel that this can somewhat still be improve.

Idea: Uses socket

Idea: use multi exec curl

Status: Pending

=== Possible improvement ===

Till now CouchDB does not yet shows its strength, I personally think we need to look into how we can integrate better with the current system by using more of the mapreduce function.

=== Possible Bug ===

CouchDB does not define its stored filed, hence some float values is saved as string, this is a problem for ADEI caching in MySQL.

Solution: ADEI do a type check and convert it accordingly (cache.php)

Status: Pending (High priority)
