memgraph

Memgraph is an ACID compliant high performance transactional distributed in-memory graph database featuring runtime native query compiling, lock free data structures, multi-version concurrency control and asynchronous IO.

dependencies

Memgraph can be compiled using any modern c++ compiler. It mostly relies on the standard template library, however, some things do require external libraries.

Some code contains linux-specific libraries and the build is only supported on a 64 bit linux kernel.

  • linux
  • clang 3.8 (good c++11 support, especially lock free atomics)
  • antlr (compiler frontend)
  • cppitertools
  • fmt format
  • google benchmark
  • google test
  • glog
  • gflags
