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>
