Scylla

What is Scylla?

Scylla is the real-time big data database that is API-compatible with Apache Cassandra and Amazon DynamoDB.Scylla embraces a shared-nothing approach that increases throughput and storage capacity to realize order-of-magnitude performance improvements and reduce hardware costs.

For more information, please see the ScyllaDB web site.

Build Prerequisites

Scylla is fairly fussy about its build environment, requiring very recentversions of the C++20 compiler and of many libraries to build. The documentHACKING.md includes detailed information on building anddeveloping Scylla, but to get Scylla building quickly on (almost) any buildmachine, Scylla offers a frozen toolchain,This is a pre-configured Docker image which includes recent versions of allthe required compilers, libraries and build tools. Using the frozen toolchainallows you to avoid changing anything in your build machine to meet Scylla'srequirements - you just need to meet the frozen toolchain's prerequisites(mostly, Docker or Podman being available).

Building Scylla

Building Scylla with the frozen toolchain dbuild is as easy as:

$ git submodule update --init --force --recursive
$ ./tools/toolchain/dbuild ./configure.py
$ ./tools/toolchain/dbuild ninja build/release/scylla

For further information, please see:

Running Scylla

To start Scylla server, run:

$ ./tools/toolchain/dbuild ./build/release/scylla --workdir tmp --smp 1 --developer-mode 1

This will start a Scylla node with one CPU core allocated to it and data files stored in the tmp directory.The --developer-mode is needed to disable the various checks Scylla performs at startup to ensure the machine is configured for maximum performance (not relevant on development workstations).Please note that you need to run Scylla with dbuild if you built it with the frozen toolchain.

For more run options, run:

$ ./tools/toolchain/dbuild ./build/release/scylla --help

Testing

See test.py manual.

Scylla APIs and compatibility

By default, Scylla is compatible with Apache Cassandra and its APIs - CQL andThrift. There is also support for the API of Amazon DynamoDB™,which needs to be enabled and configured in order to be used. For moreinformation on how to enable the DynamoDB™ API in Scylla,and the current compatibility of this feature as well as Scylla-specific extensions, seeAlternator andGetting started with Alternator.

Training

Training material and online courses can be found at Scylla University.The courses are free, self-paced and include hands-on examples. They cover a variety of topics including Scylla data modeling,administration, architecture, basic NoSQL concepts, using drivers for application development, Scylla setup, failover, compactions,multi-datacenters and how Scylla integrates with third-party applications.
