Hi all! I just recently found the "domain-metadata-cache-ttl" option. Reviewing the code it seems that this cache is only used for DNSSEC related data during handling of incoming queries. Is this correct? (it should be added to the docs).
Further I wonder if it may be useful to change the metadata loading. As far as I see, every request to a metadata triggers a database query. Hence, if 3 metadatas are querried, we have 3 DB lookups, and DB lookups are usually the slowest part in the whole answering process (at least with SQL DBs). Hence, wouldn't it make sense to load all metadata of a domain from DB on the first request for a metadata of this domain, and then cache it, or at least cache it while handling this incoming query? regards Klaus _______________________________________________ Pdns-users mailing list Pdns-users@mailman.powerdns.com https://mailman.powerdns.com/mailman/listinfo/pdns-users
