Compilation

Bazel configuration

• Create bazel configuration file with touch .bazelrc
• Add bazel configuration echo build --cxxopt="-std=c++2a" --cxxopt='-fopenmp' --linkopt='-lgomp' > .bazelrc

Bazel build

• To do a full clean build
  • bazel clean
  • bazel build //...:all
• To test
  • bazel test //...:all

CLI

• To start CLI bazel run //tools/shell:graphflowdb -- -i <serialized-graph-path>
• CLI built in commands :help get command list :clear clear shell :quit exit from shell :thread [thread] number of threads for execution :bm_debug_info debug information about the buffer manager :system_debug_info debug information about the system

• benchmark file should have the following format

name example

query
MATCH (:Person)
RETURN COUNT(*)

expectedNumOutput 8

• To run benchmark runner <benchmark-tool-binary-path> --dataset=<serialized-graph-path> --benchmark=<benchmark-file-or-folder>
  • --warmup=1 config number of warmup
  • --run=5 config number of run
  • --thread=1 config number of thread for execution

Python Driver

Current python driver is under development. See tools/python_api/test/example.py for example usage. To run this example bazel run //tools/python_api:example.
