Tomasz Grabiec 074be4d4e8 memtable, cache: Run mutation_cleaner worker in its own scheduling group
The worker is responsible for merging MVCC snapshots, which is similar
to merging sstables, but in memory. The new scheduling group will be
therefore called "memory compaction".

We should run it in a separate scheduling group instead of
main/memtables, so that it doesn't disrupt writes and other system
activities. It's also nice for monitoring how much CPU time we spend
on this.

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>
