06:51 abba Hello, I'm developing some command line tools in java. I'm afraid that starting the jvm every time I invoke the tool may take to much time. Is it possible to let the jvm run in the background and execute a jar file when requested, instead of starting the jvm every time?
08:23 pulsar not out of the box
08:24 pulsar would involve implementing some daemon service.
08:24 pulsar what are your constraints?
08:26 pulsar on modern hardware startup times for a simple hello world application should not take any longer than 1-2 sec. if this is already a problem for your budget, you will need to come up with some kind of a daemon keeping your commandline tools in a hot state.
08:26 pulsar quick search revealed http://martiansoftware.com/nailgun/ for instance.
08:27 pulsar which does address this problem. no idea if thats any good though.

11:12 pdurbin no idea if this one is any good either: Scramjet for UNIX: Java acceleration for terminal apps - https://uazu.net/scramjet/
11:12 pdurbin Hopefully, smaller, modular JVMs using Java 9 will start faster.
11:29 pulsar guys.. i need some help with terminology / design patterns.
11:30 pulsar to help me evaluate frameworks / libraries based on the documentation.
11:30 pulsar still pondering on a scalable message driven architecture
11:33 pulsar looking for search terms regarding dynamic message routing / handler instanciation.
11:34 pulsar what i needs is: message arrives at $someMQ/BUS, system routes the message to a node running a worker assigned to the message-origin (think userid). worker can be instanciated on demand if there is none.
11:35 pulsar is there a terminology for that in a classic mq system?
11:35 pulsar i guess not. i am aware of the actor model and see how it fits here.
11:39 pulsar latency is key in my usecase, i am open to suggestions in terms of framework choice.
11:59 pdurbin pulsar: I would ask whartung and Techni in #glassfish in a few hours after they're awake
12:11 pulsar ACK
