Glauber Costa 4272279bbb controllers: unify the I/O and CPU controllers
We have had so far an I/O controller, for compactions and memtables, and
a CPU controller, for memtables only -- since the scheduling was still
quota-based.

Now that the CPU scheduler is fully functional, it is time to do away
with the differences and integrate them both into one.  We now have a
memtable controller and a compaction controller, and they control both
CPU and I/O.

In the future, we may want to control processes that don't do one of
them, like cache updates. If that ever happens, we'll try to make
controlling one of them optional. But for now, since the I/O and CPU
controllers for our main two processes would look exactly the same we
should integrate them.

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>
