his series attempts to make fragments per second results reported by perf_fast_forward more stable. That includes running each test case multiple time and reporting median, median average deviation, maximum and minimum value. That should allow to relatively easily assess how repeatable the presented results are. Moreover, since perf_fast_forward does IO operation it is important that they do not introduce any excessive noise to the results. The location of the data directory is made configurable so that the user can choose less noisy disk or a ramdisk. * github.com/pdziepak/scylla.git stabilise-perf_fast_forward/v3: tests/perf_fast_forward: make fragments/s measurements more stable tests/perf_fast_forward: make data directory location configurable

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>
