Make a "compressor" an actual class, that can be implemented and registered via class registry. For "common" compressors, the objects will be shared, but complex implementors can be semi-stateful. sstable compression is split into two parts: The "static" config which is shared across shards, and a "local" one, which holds a compressor pointer. The latter is encapsulated, along with actual compressed data writers, in sstables/compress.cc. For compression (write), compression writer is instansiated with the settings active in table metadata. For decompression (read), compression reader is instansiated with the settings stored in sstable metadata, which can differ from the currently active table metadata. v2: * Structured patch sets differently (dependencies) * Added more comments/api descs * Added patch to move all sstable compression into compress.cc, effectively separating top-level virtual compressor object from sstable io knowledge v3: * Rebased v4: * Moved all sstable compression logic/knowledge into compress.cc (local compression). Merged the two patches (separation just confuses reader).
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>
