in OG-Example , how did OG understood that it has to use DbHistoricalTimeSeriesMaster implementation to read historical timeseries
I am experimenting on this branch - demo/20120201
In that branch (which to be honest, I wouldn’t recommend using as it’s just an internal marker) it’s defined in OG-Financial/config/com/opengamma/financial/demoMasters.xml. Yes, we know that’s hard to find, which is why we’ve just rolled out a completely new configuration system that replaces most of the spring with a component based system that limits the number of files involved. Full docs on that will be available in the 1.0 release.
The new config system can be seen here https://github.com/OpenGamma/OG-Platform/blob/master/projects/OG-Examples/config/fullstack/fullstack.ini
This file lists the components to be started to create a full stack server, one of which is the time-series master. The properties referenced can be found here - https://github.com/OpenGamma/OG-Platform/tree/master/projects/OG-Examples/config/fullstack . More details on the new config will follow in 1.0.
Previously, the configuration was all based on Spring. The application started a jetty server, which started a spring file (typically engine-beans.xml) which started another spring file (typically demoViewProcessor.xml) which strated other spring files including demoMasters.xml.
wow , that is one centralised powerful configuration feature indeed. thanks a ton.
