Measures if there is backpressure on an Akka Stream at the given stage.
When an Akka Stream doesn't perform as intended, it is difficult to tell where the bottleneck is, since all stages operate at the same rate (see e.g. here ).
So when things are not fast as expected, this pressure gauge can help you to narrow down on the slow stage. Imagine
| import collection.mutable.ListBuffer | |
| object NetworkUtils { | |
| def ip2Long(ip: String): Long = { | |
| val atoms: Array[Long] = ip.split("\\.").map(java.lang.Long.parseLong(_)) | |
| val result: Long = (3 to 0 by -1).foldLeft(0L)( | |
| (result, position) => result | (atoms(3 - position) << position * 8)) | |
| result & 0xFFFFFFFF | |
| } |
