In this post, we’ll look at how to combine the MDC feature of current logging framework
with Reactor's own Context, in order to make contextualized logging possible within
a reactive application.
File reading, line by line in Java… It’s never been a breeze, and until Java 8
the only high level option you had was to read the lines into a List<String>
😓
Then Java 8 came along, with its Stream interface, and a Files.lines(Path)
method that returns a Stream<String>. Turns out, this stream will lazily
read the lines from the file, without ever having to hold the whole content of
the file in memory 😍
Let’s see how we can use that with Reactor!
