It compares only timestamps, but it should use intrinsic ordering of the tombstone, which takes deletio ntime into consideration as well. If we have two range tombstones with the same timestamp but different deletion time (odd case, but still), then the one with the higher deletion time should win. That's what all other parts of the system use to resolve merges, in particular range_tombstone_list and compact_mutation_state (the fragment stream compactor). Not respecting this ordering violates the following equality: do_compact(do_compact(m1) + m2) == do_compact(m1 + m2) which may results in some clustered rows being missing in the right-hand side, but not in the left-hand side, due to differences in range tombstones. This impacts only tests currently. Message-Id: <1528705602-7218-1-git-send-email-tgrabiec@scylladb.com>
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>
