For greater throughput we need a logging mechanism that doesn't rely
on sprintf. I.e., we should consider a binary log format where we
simply pass around short message IDs (and relevant message parameters)
and use a compiled message catalog that maps IDs to text. This would
require a post-processor to read the binary log and generate
human-readable messages somewhere else. (It's obviously not a new
concept, IBM mainframes have done this for decades; the Microsoft
system logger does this as well.)
Current systems have journald, which does something like that.
I had thought of journald, but looking at its API, it seems to still primarily
work with fully-formatted messages being sent from the logging clients.
We want to be able to dump unformatted data items, and incur all the
formatting cost in the post-processor. Otherwise, we haven't gained anything
in terms of performance.
