Marin Tomic 8414479abe [StorageV2] Implement GC 
Summary:
Here are some numbers from the benchmark:

```
(TOOLCHAIN) mtomic@poso:~/memgraph/build_release$ tests/benchmark/storage_v2_gc --num-threads 8
Config: NoGc, Time: 25.9836
Config: OnFinishGc, Time: 49.012
Config: 100msPeriodicGc, Time: 45.9856
Config: 1000msPeriodicGc, Time: 40.3094
```

```
(TOOLCHAIN) mtomic@poso:~/memgraph/build_release$ tests/benchmark/storage_v2_gc --num-threads 7
Config: NoGc, Time: 20.4256
Config: OnFinishGc, Time: 39.6669
Config: 100msPeriodicGc, Time: 30.7956
Config: 1000msPeriodicGc, Time: 35.128
```

It is not that bad if there is a core dedicated to doing garbage collection.

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
