florijan 9edc472eaf Resolving TODOs in the operator implementations 
Summary:
Three TODOs resolved.

1. around line 897 - we currently don't support expansion into existing variable length edges (there is a TODO in symbol_generator.cpp:213), so this should not be done at the moment.

2. around line 1025 - This TODO was on review and nobody commented, so I'm removing it. Should have done that when the diff landed.

3. around line 1560 - This does not seem possible. Edge-uniqueness checks happen within a single `[OPTIONAL ] MATCH`. If it is OPTIONAL (the case interesting here), then the uniqueness check also gets planned under the optional branch. So, if an optional fails, the uniqueness check will get skipped, as opposed to getting executed over a Null. I added an edge-case test to verify this (and checked with the planner test).

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
