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.
