Function to reevaluate postponed compaction was called too early for strategies that don't allow parallel compaction (only leveled strategy (LCS) at this moment). Such strategies must first have the ongoing compaction deregistered before reevaluating the postponed ones. Manager uses task list of ongoing compaction to decides if there's ongoing compaction for a given column family. So compaction could stop making progress at all *if and only if* we stop flushing new data. So it could happen that a column family would be left with lots of pending compaction, leading the user to think all compacting is done, but after reboot, there will be lots of compaction activity. We'll both improve method to detect parallel compaction here and also add a call to reevaluate postponed compaction after compaction is done. Fixes #3534. Signed-off-by: Raphael S.

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>
