Answer 1

You can't limit number of records by asterisk

But you easy can rotate files by using logrotate linux utility.

For that you should create file /etc/logrotate.d/asterisk_cdr

/var/log/asterisk/cdr-csv/*csv {
missingok
rotate 5
size 2000k
create 0640 asterisk asterisk
}

For more info see documentation for logrotated
