csv file or sqlite ?

[frevol nicolas]

hi,

I am programming a filter for websites. to check if an
url is in the blacklist, i have used a csv file. i
have try to use sqlite but it looks as fast as csv
files.

Can you tell me if sqlite is faster than csv files ?
or not ?

thanks

Depends on the number of records/lines and how you access them.

If you have some kind of server and read the csv file into a set or
dictionary and query this thousands of times, it's faster than querying a
database the same amount of times.

If you have really many items in that blacklist and just query a few of
them per program run, say in a CGI script, then a database will become
faster than linear searching through a csv file.

Just try both and measure to know for sure.
