Installation on MySQL

Replacing the simple SQLite database with MySQL allows greater scalability

Create the database 1st:

mysqladmin --user=root -p create sahana
mysql -p
 GRANT USAGE ON mysql.sahana TO 'sahana'@'localhost' IDENTIFIED BY 'mypassword';

Suggest to use connection pools to reuse connections in models/00_db.py:

db=SQLDB('mysql://user:password@hostname/sahana',pools=20)

How many pools?

whatever you choose it always starts with one and grows with the
number of concurrent requests up to the value of pools (the max number
of concurrent pools). So pools should be the max number of concurrent
requests you expect. That is the max value of:
<number of requests/second> / <average time per request in seconcds>
