Size of DB table x_logs too big, 5.6+ M records

[7rdoq]

basic route for adding a new domain:
1. Add Domain: this step would create records of domain in vhost & create a new folder of this domain in HTML folder
2. Create DNS for this domain: this creates records in DB
3. Update DNS in registar

this route work like this, right?

But this too complicated, now I want:
1. edit vhost directly to add this domain & created folder directly too
2. skip this
3. update DNS

Then I restart httpd service, then without DNS of this domain (step 2), this domain still may work properly?
