Overview ¶
Package logtail keeps the most recent lines of a log in memory and streams new ones to followers.
A Tail is an io.Writer, so it can sit next to the log file behind an io.MultiWriter. Writes never block on followers: a follower that falls behind misses lines rather than slowing the logger down.
