Piotr Sarna 23df964b96 cql3: fix fetching clustering key columns for filtering
When a column is not present in the select clause, but used for
filtering, it usually needs to be fetched from replicas.
Sometimes it can be avoided, e.g. if primary key columns form a valid
prefix - then, they will be optimized out before filtering itself.
However, clustering key prefix can only be qualified for this
optimization if the whole partition key is restricted - otherwise
the clustering columns still need to be present for filtering.

This commit also fixes tests in cql_query_test suite, because they now
expect more values - columns fetched for filtering will be present as
well (only internally, the clients receive only data they asked for).

Fixes #4541

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 the build/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: build/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>
