Currently, we reserve the name ATTRS_COLUMN_NAME ("attrs") - the user
cannot use it as a key column name (key of the base table or GSI or LSI)
because we use this name for the attribute map we add to the schema.
Currently, if the user does attempt to create such a key column, the
result is undefined (sometimes corrupt sstables, sometimes outright crashes).
This patches fixes it to become a clean error, saying that this column name is
currently reserved.
The test test_create_table_special_column_name now cleanly fails, instead
of crashing Scylla, so it is converted from "skip" to "xfail".
Eventually we need to solve this issue completely (e.g., in rare cases
rename columns to allow us to reserve a name like ATTRS_COLUMN_NAME,
or alternatively, instead of using a fixed name ATTRS_COLUMN_NAME pick a
different one different from the key column names). But until we do,
better fail with a clear error instead of a crash.

Scylla
Quick-start
To get the build going quickly, Scylla offers a frozen toolchain which would build and run Scylla using a pre-configured Docker image. Using the frozen toolchain will also isolate all of the installed dependencies in a Docker container. Assuming you have met the toolchain prerequisites, which is running Docker in user mode, building and running is as easy as:
$ ./tools/toolchain/dbuild ./configure.py
$ ./tools/toolchain/dbuild ninja build/release/scylla
$ ./tools/toolchain/dbuild ./build/release/scylla --developer-mode 1
Please see HACKING.md for detailed information on building and developing Scylla.
Note: GCC >= 8.1.1 is required to compile 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>
