Marin Tomic 8c7b87d8b0 Cleanup BFS subcursors using transactional cache clean-up 
Summary:
Before I wrongly assumed `Shutdown` will always be called on Cursors and
removed BFS subcursors there. Now it is done using transactional cache clean-up
mechanism. There's a separate clean-up for `BfsSubcursorStorage` (for actual
subcursors) and `BfsRpcServer` (for database accessors created by the server).

I've changed `BfsRpcServer` to have a `GraphDbAccessor` per transaction,
instead of per `BfsSubcursor`. Mainly because there is no reliable way to check
if the transaction tied to the accessor has expired as it is not safe to call
`transaction_id` method (since `GraphDbAccessor` is holding only a reference to
`Transaction` object).

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
