Hi all, I managed to do what you want but only in hacky way:
val initStarted = new AtomicBoolean(false)
val initCompleteLatch = new CountDownLatch(1)
scenario("myScenario")
.doIf(_ => initStarted.getAndSet(true) == false) {
exec(http("first")
.get("/endpoint")
.check(status.is(200),
jsonPath("$..response.id").findAll.saveAs("reponseVariable")
)
).exec { session =>
reponseVariable = session("reponseVariable").as[String]
initCompleteLatch.countDown()
session
}
}
.exec { session =>
initCompleteLatch.await()
session.set("reponseVariable", reponseVariable)
}
.exec(http("second")
.post("/another/endpoint/{responseVariable}")
.body(...)
.check(status.is(200))
)
Hope it helps :) It can chain serveral requests, passthrough response along, and ensures first request is send only once.

Slony-I is a "master to multiple slaves" replication system for PostgreSQL supporting cascading (e.g. - a node can feed another node which feeds another node...) and failover.
The big picture for the development of Slony-I is that it is a master-slave replication system that includes all features and capabilities needed to replicate large databases to a reasonably limited number of slave systems.
Slony-I is a system designed for use at data centers and backup sites, where the normal mode of operation is that all nodes are available.
A fairly extensive "admin guide" comprising material in the Git tree may be found here. There is also a local copy.

The Little Book of Semaphores is a free (in both senses of the word) textbook that introduces the principles of synchronization for concurrent programming. In most computer science curricula, synchronization is a module in an Operating Systems class. OS textbooks present a standard set of problems with a standard set of solutions, but most students don't get a good understanding of the material or the ability to solve similar problems. The approach of this book is to identify patterns that are useful for a variety of synchronization problems and then show how they can be assembled into solutions. After each problem, the book offers a hint before showing a solution, giving students a better chance of discovering solutions on their own. The book covers the classical problems, including "Readers-writers," "Producer-consumer", and "Dining Philosophers." In addition, it collects a number of not-so-classical problems
