There are two complimentary requests regarding not logging certain resolutions to queries table: this one about ignoring certain domains and another about ignoring certain clients.
Pi-Hole already knows how to very efficiently decide what to do with requests based on the set of rules. It would be amazing to be able to also define what it should do with logging based on a similar set of rules (e.g. client's group, domain, decision to block or allow etc). It should cover both requests very nicely.
In my particular situation I have a Chinese IoT that tries to access baidu.com every couple of seconds. It is always blocked but it does not prevent anything, and the FTL database grows several hundred thousands records every week. Deleting them manually and truncating statistics is very boring to say the least...
