> I'd argue that the first line of attack on that should be to explain to those consumers of logs that they are making some unwarranted assumptions about the kind of inputs they'll be seeing. PostgreSQL's CSV log formats are not a particular bizarre format, or very difficult to parse. The standard Python CSV library handles them just file, for example. You have to handle newlines that are part of a log message somehow; a newline in a PostgreSQL query, for example, needs to be emitted to the logs.
I believe the (valid) root reason behind this assumption is to care for resource consumption during stream processing. There are solutions to that problem (as the multi line mode of fuent bit already exposed before in this thread), but they are not specifically reliable, nor easy to maintain. Not claiming this assumption does imply parsing of a *rolling* set of log lines with *previously unkown cardinality*. That's expensive on computing resources. I don't have actual numbers, but it doesn't seem too far fetched, neither. I filed a question to the author of fluent-bit to that extend which you can consult here: https://github.com/fluent/fluent-bit/issues/564 Let's see what Eduardo has to inform us about this...
