A complete server using Akka streams that reads some source, batches its data and then publishes. If the data cannot be published then it backs off with a best-effort of sending that data again.
val (recycleQueue, recycleSource) =
Source
.queue[SoilStateReading](100, OverflowStrategy.dropTail)
.prefixAndTail(0)
.map(_._2)
.toMat(Sink.head)(Keep.both)
.run()
StreamConverters.fromInputStream(() => this.getClass.getClassLoader.getResourceAsStream("sensors.log"))
.via(SoilStateReading.csvParser)
.merge(Source.fromFutureSource(recycleSource))

resolving merge conflicts with magit-ediff

Use magit-ediff to resolve merge conflicts

Use magit-ediff or 'e' on an unmerged item to resolve merge conflicts with ediff. Magit will set up an ediff with three buffers A, B and C. A and B are the original (conflicting) files, and C is the conflicted merge.

Use 'n'/'p' to move to the next/previous conflict, use 'a'/'b' to choose which changes (those in a A or B) should be the ones to keep in the merged file.

You can always just switch to buffer C and edit what the merged version should look like.
