Single Node, Memory Only Emulator for Google Bigtable

This is a single-node, non-persistent emulator for Google's Bigtable.

It should pass all the integration tests in Google's C++ client repository (google-cloud-cpp), except those that must run against production Bigtable.

Dependencies

The Bigtable-emulator depends on google-cloud-cpp (which the build tools retrieve and build automatically) and the abseil library. Other dependencies such as GRPC are provided by google-cloud-cpp.

Building

Building the Bigtable emulator requires bazel.

bazel build //...

Running the Unit Tests

bazel test //...

Running clang-tidy with Bazel

bazel build --config clang-tidy //...

Running the Emulator

bigtable-emulator -p <port>

Development

It's a good idea to set home ($HOME/.bazelrc on Unixes) or system bazelrc and enable compilation cache there with this line:

build --disk_cache=~/.cache/bazel/disk-cache

Note that the cache directory grows indefinitely.

Formatting the code

# On bash you neet to enable globstar with `shopt -s globstar` first
clang-format -i -style=file -assume-filename=.clang-format **/*.cc **/*.h

compile_commands.json

If you need to generate compile_commands.json for your tooling, run:

bazel run --config=compile-commands
