Botond Dénes 9a1bd24d82 query_mutations_on_all_shards(): pause looked-up readers
On the beginning of each page, all saved readers from the previous pages
(if any) are looked up, so they can be reused. Some of these saved
readers can end up not being used at all for the current page, in which
case they will needlessly sit on their permit for the duration of
filling the page. Avoid this by immediately pausing all looked-up
readers. This also allows a nice unifying of the reader saving logic, as
now *all* readers will be in a paused state when `save_reader()` is
called. Previously, looked-up, but not used readers were an exception to
this, requiring extra logic to handle both cases. This logic can now be
removed.

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.

Note: GCC >= 8.1.1 is require to compile Scylla.

Note: See frozen toolchain for a way to build and run on an older distribution.

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>
