Tomasz Grabiec 2ffb621271 Merge "Fix atomic_cell_or_collection::external_memory_usage()" from Paweł
After the transition to the new in-memory representation in
aab6b0ee27 'Merge "Introduce new in-memory
representation for cells" from Paweł'
atomic_cell_or_collection::external_memory_usage() stopped accounting
for the externally stored data. Since, it wasn't covered by the unit
tests the bug remained unnotices until now.

This series fixes the memory usage calculation and adds proper unit
tests.

* https://github.com/pdziepak/scylla.git fix-external-memory-usage/v1:
  tests/mutation: properly mark atomic_cells that are collection members
  imr::utils::object: expose size overhead
  data::cell: expose size overhead of external chunks
  atomic_cell: add external chunks and overheads to
    external_memory_usage()
  tests/mutation: test external_memory_usage()

Scylla

Quick-start

$ git submodule update --init --recursive
$ sudo ./install-dependencies.sh
$ ./configure.py --mode=release
$ ninja-build -j4 # Assuming 4 system threads.
$ ./build/release/scylla
$ # Rejoice!

Please see HACKING.md for detailed information on building and developing Scylla.

Running Scylla

  • Run Scylla
./build/release/scylla

  • run Scylla with one CPU and ./tmp as data directory
./build/release/scylla --datadir tmp --commitlog-directory tmp --smp 1
  • For more run options:
./build/release/scylla --help

Building Fedora RPM

As a pre-requisite, you need to install Mock on your machine:

# Install mock:
sudo yum install mock

# Add user to the "mock" group:
usermod -a -G mock $USER && newgrp mock

Then, to build an RPM, run:

./dist/redhat/build_rpm.sh

The built RPM is stored in /var/lib/mock/<configuration>/result directory. For example, on Fedora 21 mock reports the following:

INFO: Done(scylla-server-0.00-1.fc21.src.rpm) Config(default) 20 minutes 7 seconds
INFO: Results and/or logs in: /var/lib/mock/fedora-21-x86_64/result

Building Fedora-based Docker image

Build a Docker image with:

cd dist/docker
docker build -t <image-name> .

Run the image with:

docker run -p $(hostname -i):9042:9042 -i -t <image name>
