Folks this is meant to be an honest question, not a snarky comment. I'm not a DBA, I'm DevOps/SRE and logs for me always meant execution logs. I'm just curious if between those involved in database domain logs is used to refer to WAL.

I think the original poster in this thread was joking. A fair number of databases use "logs" as a core mechanism for storing and sorting data. "Logs" in this context is not to be confused with stdout/stderr output that you may collect from a running program and forward somewhere like Cloudwatch/Elasticsearch etc. "Logs" in the context of databases here refers to the data structure; which can generally be defined as simply an append-only "file" (I put file in quotes because just because something is a log does not mean it is necessarily written to disk yet - that's why write-ahead logs exist). It's not just write-ahead logs.

Google "Log-structured merge trees" if you want an interesting read.
