Logs Logs (in a very degenerative sense) are a series of events/statements that act like the breadcrumb for the things that happened. Degenerative as I am referring mostly as application or software logs. (More pure meaning would be let’s say database logs which are used for replication process or a series of events for active state machine replication). I want to talk about the logs (application logs, system logs). For interested reader, I highly recommend I heart logs which talks about the power of logs in a distributed systems - how a series of immutable logs help us chronologically capture a series of events and computing/coming to consensus/committing transaction etc on top of it.
