• 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

Debugging

curl 'http://localhost/adei/services/getdata.php?db_server=edelweiss&db_name=automat_monthly&db_group=edelweiss&window=-5&db_mask=0,3'

http://localhost/adei/services/list.php?target=servers

curl 'http://localhost/adei/services/getdata.php?db_server=edelweiss&db_name=automat_weekly_adei&db_group=edelweiss&window=1307357533-1384790080&db_mask=0,1&resample=86400'

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
