Thanks Rainer. Interesting. I read chapter 7 about concurrency optimization. What I am looking for is indeed what is described there: preserved timestamp order. And this only with some restrictions: * in time windows within few seconds or so because those message will be processed with the need of chronological order. * only per system Of course there might be corner cases where this will not always work but this will then be only due to a system outage or something like that. I am now going to try 5.6.0 with omruleset. I hope it will work then. Are there any config options to control or affect timestamp ordering? In my case I guess it would be sufficient if only one thread would feed the database.
