This allows for us to delete an existing snapshot. It works at the column family level, and removing it from the list of keyspace snapshots needs to happen only when all CFs are processed. Therefore, that is provided as a separate operation. The filesystem code is a bit ugly: it can be made better by making our file lister more generic. First step would be to call it walker, not lister... For now, we'll use the fact that there are mostly two levels in the snapshot hierarchy to our advantage, and avoid a full recursion - using the same lambda for all calls would require us to provide a separate class to handle the state, that's part of making this generic.

#Scylla
##Building Scylla
In addition to required packages by Seastar, the following packages are required by Scylla.
Submodules
Scylla uses submodules, so make sure you pull the submodules first by doing:
git submodule init
git submodule update --recursive
Building scylla on Fedora
Installing required packages:
sudo yum install yaml-cpp-devel lz4-devel zlib-devel snappy-devel jsoncpp-devel thrift-devel antlr3-tool antlr3-C++-devel libasan libubsan
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 -i -t <image name>
