Pekka Enberg d2632ddf1d Merge "gossip: optimize apply_state_locally for large cluster" from Asias
"This series tries to improve the bootstrap of a node in a large cluster by
improving how gossip applies the gossip node state. In #2404, the joining node
failed to bootstrap, because it did not see the seed node when
storage_service::bootstrap ran. After this series, we apply the whole gossip
state contained in the gossip ack/ack2 message before applying the next one,
and we apply the state of the seed node earlier than non-seed node so we can
have the seed node's state faster. We also add some randomness to the order of
applying gossip node state to prevent some of the nodes' state are always
applied earlier than the others.

This series improves apply_state_locally for large cluster:

 - Tune the order of applying endpoint_state
 - Serialize apply_state_locally
 - Avoid copying of the gossip state map

Fixes #2404"

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>
