Marin Tomic 6894e2aef8 Distributed BFS filter lambda 
Summary:
TODO:

~~1. Figure out how to propagate exceptions during lambda evaluation to master.~~

~~2. Make some more complicated test cases to see if everything is~~
~~sent over the network properly (lambdas depending on frame, evaluation context).~~

~~3. Support only `GraphView::OLD`.~~

4. [MAYBE] Send only parts of the frame necessary for lambda evaluation.

~~5. Fix EdgeType handling~~

--------------------

Serialize frame and send it in PrepareForExpand RPC

Move Lambda out of ExpandVariable

Send symbol table and filter lambda in CreateBfsSubcursor RPC

Evaluate filter lambda during the expansion

Send evaluation context in CreateBfsSubcursor RPC

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
