What is the archive database?
It is possible to store scalar data in a database instead of netcdf-files on disk. At the moment the only supported database type is MongoDB. It is however possible to add support for other database types as well by implementing a set of java interfaces.
The archive database should be considered as an optional extension to the Deltares Open Archive to store scalar data in a way which is more convenient to your organization.
Storing data in MongoDB instead of Netcdf-files has the following advantages:
- Data is directly available. It is not necessary to run the harvester.
- Reading data from MongoDB by using seamless integration is more performant in comparison to reading from Netcdf-files,
- MongoDB prevents that data is stored multiple times in the archive.
The MongoDB implementation was developed in close cooperation with TVA and Infisys.
How to configure the archive database?
The archive database should be configured in the Archives.xml. In this file the configuration can configure were the database is located and from which location the database plugin should be loaded.
More information about the configuration of the Archives.xml can be found here.
