Teon Banek 8380d3694f Raise semantic error when redeclaring node in MERGE 
Summary:
openCypher expects MERGE to behave like CREATE. As such, it shouldn't be
allowed to refer to declared nodes, while providing labels and
properties.

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
  • yaml-cpp
