Tomasz Grabiec c31dff8211 Merge 'Skip inside wide partitions using index (rows only)' from Vladimir
This patchset adds support for skipping inside wide partitions using
index for sliced queries. This can significantly reduce disk I/O for
queries that only need to read a small amount of data from a wide
partition.

Other changes include general code clean-up and simplification.

 * github.com/argenet/scylla.git tree/projects/sstables-30/skip_using_index/v6:
  sstables: Support resetting data_consume_rows_context_m to
    indexable_element::cell.
  tests: Add tests to cover skipping with index through SSTables 3.x.
  sstables: Support skipping inside wide partitions using index.
  to_string: Add operator<< overload for std::optional.
  sstables: Use std::optional instead of std::experimental::optional.

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>
