Teon Banek 0aee18544d Add caching VerticesCount during planning and estimation 
Summary:
Benchmark planning and estimating indexed ScanAll. According to the benchmark,
caching speeds up the whole process of planning and estimation by a factor of
2. Most of the performance gain is in the `CostEstimator` itself, due to plenty
of calls to `VerticesCount` when estimating all of the generated plans.

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
