03e200df5dc283f24a6a349f0b31d3eab26da893Mark Andrews * the dns_data primary. NO - The point of this driver is
03e200df5dc283f24a6a349f0b31d3eab26da893Mark Andrews * lookup performance.
03e200df5dc283f24a6a349f0b31d3eab26da893Mark Andrews * 2) Blow up database size by storing DNS data twice. Once for
03e200df5dc283f24a6a349f0b31d3eab26da893Mark Andrews * the lookup (dns_data) database, and a second time for the zone
03e200df5dc283f24a6a349f0b31d3eab26da893Mark Andrews * transfer (dns_xfr) database. NO - That would probably require
03e200df5dc283f24a6a349f0b31d3eab26da893Mark Andrews * a larger cache to provide good performance. Also, that would
03e200df5dc283f24a6a349f0b31d3eab26da893Mark Andrews * make the DB larger on disk potentially slowing it as well.
03e200df5dc283f24a6a349f0b31d3eab26da893Mark Andrews * 3) Loop through the dns_xfr database with a cursor to get
03e200df5dc283f24a6a349f0b31d3eab26da893Mark Andrews * all the different hosts in a zone. Then use the zone & host
03e200df5dc283f24a6a349f0b31d3eab26da893Mark Andrews * together to lookup the data in the dns_data database. YES -
03e200df5dc283f24a6a349f0b31d3eab26da893Mark Andrews * This may slow down zone xfr's a little, but that's ok they
