This patch adds the missing view building code to the eponymous class. We consume from the reader associated with each base table until all its views are built. If the reader reaches the end and there are incomplete views, then a view was added while others were being built. In such cases, we restart the reader to the beginning of the current token, but not to the beginning of the token range, when the view is added. Then, when we exhaust the reader, we simply create a new one for the whole token range, and resume building the pending views. We aim to be resource-conscious. On a given shard, at any given moment, we consume at most from one reader. We also strive for fairness, in that each build step inserts entries for the views of a different base. Each build step reads and generates updates for batch_size rows. We lack a controller, which could potentially allow us to go faster (to execute multiple steps at the same time, or consume more rows per batch), and also which would apply backpressure, so we could, for example, delay executing a build step.

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>
