Asias He cf6f4a5185 gossip: Introduce the shadow_round_ms option
It specifies the maximum gossip shadow round time. It can be used to
reduce the gossip feature check time during node boot up.
For instance, when the first node in the cluster, which listed both
itself and other node as seed in the yaml config, boots up, it will try
to talk to other seed nodes which are not started yet. The gossip shadow
round will be used to fetch the feature info of the cluster. Since there
is no other seed node in the cluster, the shadow round will fail. User
can reduce the default shadow_round_ms option to reduce the boot time.

Fixes #2615

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>
