Which database primarily depends on how you many indexable and unique columns you have, on the ratio of readers to writers. sqlite? LOL. I was thinking more along the lines of MySQL or BerkelyDB/SleepyCat DB .

apache::session::lock::mysql
Apache::Session::Lock::MySQL(3pm) User Contributed Perl Documentation Apache::Session::Lock::MySQL(3pm)
NAME
Apache::Session::Lock::MySQL - Provides mutual exclusion using MySQL
SYNOPSIS
use Apache::Session::Lock::MySQL;
my $locker = Apache::Session::Lock::MySQL->new();
$locker->acquire_read_lock($ref);
$locker->acquire_write_lock($ref);
$locker->release_read_lock($ref);
$locker->release_write_lock($ref);
$locker->release_all_locks($ref);
DESCRIPTION
Apache::Session::Lock::MySQL fulfills the locking interface of Apache::Session. Mutual exclusion is achieved through the use of MySQL's
GET_LOCK and RELEASE_LOCK functions. MySQL does not support the notion of read and write locks, so this module only supports exclusive
locks. When you request a shared read lock, it is instead promoted to an exclusive write lock.
CONFIGURATION
The module must know how to connect to your MySQL database to acquire locks. You must provide a datasource name, a user name, and a
password. These options are passed in the usual Apache::Session style, and are very similar to the options for
Apache::Session::Store::MySQL. Example:
tie %hash, 'Apache::Session::MySQL', $id, {
LockDataSource => 'dbi:mysql:database',
LockUserName => 'database_user',
LockPassword => 'K00l'
};
Instead, you may pass in an already opened DBI handle to your database.
tie %hash, 'Apache::Session::MySQL', $id, {
LockHandle => $dbh
};
