There is a mismatch between row markers used in SSTables 2.x (ka/la) and liveness_info used by SSTables 3.x (mc) in that a row marker can be written as a deleted cell but liveness_info cannot. To handle this, for a dead row marker the corresponding liveness_info is written as expiring liveness_info with a fake TTL set to 1. This approach is adapted from the solution for CASSANDRA-13395 that exercised similar issue during SSTables upgrades. * github.com/argenet/scylla.git projects/sstables-30/dead-row-marker/v7: sstables: Introduce TTL limitation and special 'expired TTL' value. sstables: Write dead row marker as expired liveness info. tests: Add test covering dead row marker writing to SSTables 3.x.

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>
