Teon Banek b69c162c9f Add base QueryException class 
Summary:
Also, inherit `TypedValueException` from `BasicException` instead of
`StacktraceException`.

This is meant as a basic API change, so that catching query exceptions becomes
simpler. The error message can be obtained from `what` method, inherited from
`BasicException`. In the future, we may extend the `QueryException`. It could
take column/row position in query source, as well as other information. Then
provide (or override `what`) a method to format the error message nicely for
the user.

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
