"
We are seeing some workloads with large datasets where the compaction
controller ends up with a lot of shares. Regardless of whether or not
we'll change the algorithm, this patchset handles a more basic issue,
which is the fact that the current controller doesn't set a maximum
explicitly, so if the input is larger than the maximum it will keep
growing without bounds.
It also pushes the maximum input point of the compaction controller from
10 to 30, allowing us to err on the side of caution for the 2.2 release.
"
* 'tame-controller' of github.com:glommer/scylla:
controller: do not increase shares of controllers for inputs higher than the maximum
controller: adjust constants for compaction controller

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>
