Haskell bindings for the FoundationDB C client. Not entirely finished, but quite usable. Currently contains FFI bindings to all of the C API, a Transaction monad for running transactions (example), and implementations of the standard tuple, subspace and directory layers.
I am not using this in a production-like context, but I have exercised the code rather heavily (heavy transaction rates for days at a time) in both local and cloud environments. The major missing component is directory partitions, but I haven't needed them yet. Generally speaking, the directory layer is the least exercised part of the library.
Supported FoundationDB versions
Currently supports 5.2.x, 6.0.x, and 6.1.x.
Generating options from fdb.options
FoundationDB provides a specification of available client options. We generate the FoundationDB.Options module from this file with the generate-options executable in this project.
To build the generate-options executable, pass the with-generate-options flag
when building. For example, when building with stack, the command is
stack build --flag foundationdb-haskell:with-generate-options
You can then invoke it on fdb.options.
stack exec generate-options -- --file /usr/include/foundationdb/fdb.options > src/FoundationDB/Options.hs
