dtlvnative

Provides pre-built native dependencies for Datalevin database. This is done by packaging the compiled native libraries and JavaCPP JNI library files in the platform specific JAR files.

In addition to JavaCPP's JNI library, these native libraries are included:

• lmdb LMDB key value library.
• dtlv wraps LMDB and implements Datalevin comparator, iterators, counters and samplers.
• usearch Vector indexing and similartiy search library.

The following platforms are currently supported:

• macosx-arm64
• macosx-x86_64
• linux-arm64
• linux-x86_64
• windows-x86_64

The name of the released JAR is org.clojars.huahaiy/dtlvnative-PLATFORM, where PLATFORM is one of the above.

Additional dependencies

Right now, the included shared libraries depend on some system libraries.

• libc
• libomp or libgomp
• libmvec

On systems that these are not available by default, you will have to install them yourself. For example, on Ubuntu/Debian, apt install libgomp1, or apt install gcc-12 g++-12; on MacOS, brew install libomp libllvm

Building these into our jars statically is a future work. PR is always welcome.
