That is a Cassandra message and means this is either a Cassandra or lazyboy
problem, and should be followed up in either of those communities.

 Sorry, the message internal error doesn't give us much to go on.
 Maybe the server had a problem?

Thrift / Scala concurrency issue

2009-09-16 Thread Sebastian Latza 

Hi everybody,

while Scala isn''t natively supported by Thrift, maybe someone has  
seen the same problem I'm facing.
I have got a very simple Thrift service which is doing some processing  
(100 to 1000ms) and then returns the result back to the client. When  
benchmarking I noticed that when adding more concurrent clients the  
performance degraded: while one client was getting 10 req/sec, two  
were getting 5 req/sec, and so on. So the server is handling the  
requests sequential for some reason. I have tried all implementations  
(TThreadPoolServer, TNonblockingServer, THsHaServer) with the same  
results. The implementation is quite vanilla:


// Includes here...

class ServiceHandler() extends service.Iface {
override def call_function(String: foo) : String = {
Thread.sleep(100)
return result
}
}

object server {
 def main(args: Array[String]) {
   val processor = new service.Processor(new ServiceHandler())
   val socket = new TNonblockingServerSocket(9090)
   val server = new TNonblockingServer(processor, socket)
   server.serve()
}

Java 1.6.0_16, Scala 2.7.5, same results on Mac and Linux.

Any hints what I might be running into here?

Regards
Sebastian
