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.
Runtime dependencies:
- eccodes
- eckit
- 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
