How to drop a log record if it cannot be parsed?

[gajus]

I've configured a parser using Kubernetes labels:

fluentbit.io/parser: airbyte

The parser itself looks like so:

[PARSER]
    name airbyte
    format regex
    -- https://regex101.com/r/lSdtR8/1
    regex ^(?<time>\d{4}-\d{2}-\d{2}\s\d{2}:\d{2}:\d{2})\s(?<severity>[^ ]*)\s(?<namespace>[^ ]*)\s-\s(?<message>.*)$

My problem is that the target pods are producing logs in a variety of formats that do not conform with the parser, many of which I do not care for. Those logs effective skip the parser.

Is there a way for me to entirely trop those logs if they do not match the parser?

At the moment, I need to write a filter for every possible log format they produce, e.g.

[FILTER]
    name grep
    match *
    # These are low value/high noise (LVHN) logs produced by airbyte workers
    # https://regex101.com/r/IIFK6X/1
    exclude log /^Log4j2Appender says:/
    # following by many more exclude rules...

which feels like a losing battle
