Summary: Fixed distributed init. Add CMakeLists to build experimentall/distribuedClosing unused Channels, work in progress. Make System the owner of Reactor. This entails changing shared_ptr -> unique_ptr and some pointers to references. Merged experimental repository into memgraph. Moved experimental repo to experimental directory. Removed obsolete experimental files. Added comments. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Subscription service unsubscribe. Add Close method on EventStream. Add placeholder for the configuration class. Remove comments. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Clean-up parameters for EventQueue. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Add Channel::serialize method implementation. Merge. Add docs on event stream. Clang-format merge conflicts. First implementations of serialize methods. Add hostname, port, and names as methods in Channel base class. Add reactor name and name methods to LocalChannel. Add reactor name to LocalChannel. Add name to LocalChannel. Add serialization service. Serialize_test removed. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Move Message to the end of communications files. Full example of serialization with cereal. Fix constructor calls. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Avoid using `FindChannel` in the transaction code. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Init script creates libs folder. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Add System pointer to Network. serialized_test binary is removed from the repo. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Cereal basic example. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Callbacks finished. Always open the main channel by default. Fixed callbacks, wrong number of emplace arguments. Callbacks WIP. Raise connector mutex to reactor level. Add argument to LockedPush. Fix data race in connector closing. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Add functional header. Fixed to make the changes work. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Refactored connectors into Reactors Use shared pointer for the mutex. Rename to Open and Close in implementation file. Rename Create to Open and Destroy to Close. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Adding callback to Reactors; work in progress Add stubs for asynchronous channel resolution. Add stubs for the networking service. Replace reactor pointers with shared ptrs, disable System assignment. Forbid assignment. Replace raw channel pointers with shared pointers. Replace raw event stream pointer with shared pointer. Rename default stream name. Use recursive mutex in System. Main uses Spawn method. All files are formatted. Move thread local to a cpp file. Work in progress on Spawn method. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Kill out graph.hpp to make it compile Add Spawn method prototype. Fix return type. Merge branch 'master' of https://phabricator.memgraph.io/source/experimental Add method used to create nameless channels. Add format script. Introduce the Reactor base class.

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
