The document\n[HACKING.md](HACKING.md) includes detailed information on building and\ndeveloping Scylla, but to get Scylla building quickly on (almost) any build\nmachine, Scylla offers a [frozen toolchain](tools\u002Ftoolchain\u002FREADME.md).\nThis is a pre-configured Docker image which includes recent versions of all\nthe required compilers, libraries and build tools. Using the frozen toolchain\nallows you to avoid changing anything in your build machine to meet Scylla's\nrequirements - you just need to meet the frozen toolchain's prerequisites\n(mostly, Docker or Podman being available).\n\n## Building Scylla\n\nBuilding Scylla with the frozen toolchain `dbuild` is as easy as:\n\n```bash\n$ git submodule update --init --force --recursive\n$ .\u002Ftools\u002Ftoolchain\u002Fdbuild .\u002Fconfigure.py\n$ .\u002Ftools\u002Ftoolchain\u002Fdbuild ninja build\u002Frelease\u002Fscylla\n```\n\nFor further information, please see:\n\n* [Developer documentation] for more information on building Scylla.\n* [Build documentation] on how to build Scylla binaries, tests, and packages.\n* [Docker image build documentation] for information on how to build Docker images.\n\n[developer documentation]: HACKING.md\n[build documentation]: docs\u002Fdev\u002Fbuilding.md\n[docker image build documentation]: dist\u002Fdocker\u002Fredhat\u002FREADME.md\n\n## Running Scylla\n\nTo start Scylla server, run:\n\n```bash\n$ .\u002Ftools\u002Ftoolchain\u002Fdbuild .\u002Fbuild\u002Frelease\u002Fscylla --workdir tmp --smp 1 --developer-mode 1\n```\n\nThis will start a Scylla node with one CPU core allocated to it and data files stored in the `tmp` directory.\nThe `--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).\nPlease note that you need to run Scylla with `dbuild` if you built it with the frozen toolchain.\n\nFor more run options, run:\n\n```bash\n$ .\u002Ftools\u002Ftoolchain\u002Fdbuild .\u002Fbuild\u002Frelease\u002Fscylla --help\n```\n\n## Testing\n\n[![Build with the latest Seastar](https:\u002F\u002Fgithub.com\u002Fscylladb\u002Fscylladb\u002Factions\u002Fworkflows\u002Fseastar.yaml\u002Fbadge.svg)](https:\u002F\u002Fgithub.com\u002Fscylladb\u002Fscylladb\u002Factions\u002Fworkflows\u002Fseastar.yaml) [![Check Reproducible Build](https:\u002F\u002Fgithub.com\u002Fscylladb\u002Fscylladb\u002Factions\u002Fworkflows\u002Freproducible-build.yaml\u002Fbadge.svg)](https:\u002F\u002Fgithub.com\u002Fscylladb\u002Fscylladb\u002Factions\u002Fworkflows\u002Freproducible-build.yaml) [![clang-nightly](https:\u002F\u002Fgithub.com\u002Fscylladb\u002Fscylladb\u002Factions\u002Fworkflows\u002Fclang-nightly.yaml\u002Fbadge.svg)](https:\u002F\u002Fgithub.com\u002Fscylladb\u002Fscylladb\u002Factions\u002Fworkflows\u002Fclang-nightly.yaml)\n\nSee [test.py manual](docs\u002Fdev\u002Ftesting.md).\n\n## Scylla APIs and compatibility\nBy default, Scylla is compatible with Apache Cassandra and its API - CQL.\nThere is also support for the API of Amazon DynamoDB™,\nwhich needs to be enabled and configured in order to be used. For more\ninformation on how to enable the DynamoDB™ API in Scylla,\nand the current compatibility of this feature as well as Scylla-specific extensions, see\n[Alternator](docs\u002Falternator\u002Falternator.md) and\n[Getting started with Alternator](docs\u002Falternator\u002Fgetting-started.md).\n\n## Documentation\n\nDocumentation can be found [here](docs\u002Fdev\u002FREADME.md).\nSeastar documentation can be found [here](http:\u002F\u002Fdocs.seastar.io\u002Fmaster\u002Findex.html).\nUser documentation can be found [here](https:\u002F\u002Fdocs.scylladb.com\u002F).\n\n## Training\n\nTraining material and online courses can be found at [Scylla University](https:\u002F\u002Funiversity.scylladb.com\u002F).\nThe courses are free, self-paced and include hands-on examples. They cover a variety of topics including Scylla data modeling,\nadministration, architecture, basic NoSQL concepts, using drivers for application development, Scylla setup, failover, compactions,\nmulti-datacenters and how Scylla integrates with third-party applications.\n\n## Contributing to Scylla\n\nIf you want to report a bug or submit a pull request or a patch, please read the [contribution guidelines].\n\nIf you are a developer working on Scylla, please read the [developer guidelines].\n\n[contribution guidelines]: CONTRIBUTING.md\n[developer guidelines]: HACKING.md\n\n## Contact\n\n* The [community forum] and [Slack channel] are for users to discuss configuration, management, and operations of ScyllaDB.\n* The [developers mailing list] is for developers and people interested in following the development of ScyllaDB to discuss technical topics.\n\n[Community forum]: https:\u002F\u002Fforum.scylladb.com\u002F\n\n[Slack channel]: http:\u002F\u002Fslack.scylladb.com\u002F\n\n[Developers mailing list]: https:\u002F\u002Fgroups.google.com\u002Fforum\u002F#!forum\u002Fscylladb-dev\n","Scylla是一个使用Seastar框架构建的NoSQL数据存储系统，兼容Apache Cassandra和Amazon DynamoDB。其核心功能包括高性能的数据处理能力、API兼容性以及通过无共享架构实现的高吞吐量与存储容量扩展。技术特点方面，Scylla利用了现代C++特性，并且对编译环境有着严格要求，支持通过预配置的Docker镜像简化开发设置。适用于需要实时处理大规模数据集的应用场景，特别是在那些对性能有极高要求而同时希望减少硬件成本的情况下。",2,"2026-06-11 03:28:10","top_topic"]
