FDB (Fields DataBase) is a domain-specific object store developed at ECMWF for storing, indexing and retrieving GRIB data. Each GRIB message is stored as a field and indexed trough semantic metadata (i.e. physical variables such as temperature, pressure, ...). A set of fields can be retrieved specifying a request using a specific language developed for accessing MARS Archive
FDB exposes a C++ API as well as CLI tools.

---|---|
eckit: | http://github.com/ecmwf/eckit |
metkit: | http://github.com/ecmwf/metkit |
Build dependencies:
CMake: | For use and installation see http://www.cmake.org/ |
---|---|
ecbuild: | ECMWF library of CMake macros () |
fdb employs an out-of-source build/install based on CMake.
Make sure ecbuild is installed and the ecbuild executable script is found ( which ecbuild
).
Now proceed with installation as follows:
# Environment --- Edit as needed srcdir=$(pwd) builddir=build installdir=$HOME/local # 1. Create the build directory: mkdir $builddir cd $builddir # 2. Run CMake ecbuild --prefix=$installdir -- -DCMAKE_INSTALL_PREFIX=</path/to/installations> $srcdir # 3. Compile / Install make -j10 make install
Two publications, co-authored by Simon D. Smart, Tiago Quintino, Baudouin Raoult describe fdb architecture and have been presented at PASC'17 A Scalable Object Store for Meteorological and Climate Data and PASC'19 A High-Performance Distributed Object-Store for Exascale Numerical Weather Prediction and Climate
