This patch series adds error handling for streaming failure during topology operations instead of an infinite retry. If streaming fails the operation is rolled back: bootstrap/replace nodes move to left and decommissioned/remove nodes move back to normal state. * 'gleb/streaming-failure-rollback-v4' of github.com:scylladb/scylla-dev: raft: make sure that all operation forwarded to a leader are completed before destroying raft server storage_service: raft topology: remove code duplication from global_tablet_token_metadata_barrier tests: add tests for streaming failure in bootstrap/replace/remove/decomission test/pylib: do not stop node if decommission failed with an expected error storage_service: raft topology: fix typo in "decommission" everywhere storage_service: raft topology: add streaming error injection storage_service: raft topology: do not increase topology version during CDC repair storage_service: raft topology: rollback topology operation on streaming failure. storage_service: raft topology: load request parameters in left_token_ring state as well storage_service: raft topology: do not report term_changed_error during global_token_metadata_barrier as an error storage_service: raft topology: change global_token_metadata_barrier error handling to try/catch storage_service: raft topology: make global_token_metadata_barrier node independent storage_service: raft topology: split get_excluded_nodes from exec_global_command storage_service: raft topology: drop unused include_local and do_retake parameters from exec_global_command which are always true storage_service: raft topology: simplify streaming RPC failure handling
ScyllaDB Documentation
This repository contains the source files for ScyllaDB Open Source documentation.
- The
devfolder contains developer-oriented documentation related to the ScyllaDB code base. It is not published and is only available via GitHub. - All other folders and files contain user-oriented documentation related to ScyllaDB Open Source and are sources for docs.scylladb.com.
To report a documentation bug or suggest an improvement, open an issue in GitHub issues for this project.
To contribute to the documentation, open a GitHub pull request.
Key Guidelines for Contributors
- Follow the ScyllaDB Style Guide.
- The user documentation is written in reStructuredText (RST) - a plaintext markup language similar to Markdown. If you're not familiar with RST, see ScyllaDB RST Examples.
- The developer documentation is written in Markdown. See Basic Markdown Syntax for reference.
Creating Knowledge Base Articles
The kb/ directory holds source files for knowledge base articles in the Knowledge Base section of the ScyllaDB documentation.
The kb/kb_common subdirectory contains a template for knowledge base articles to help you create new articles.
To create a new knowledge base article (KB):
- Copy the
kb-article-template.rstfile from/kb/kb_commonto/kband rename it with a unique name. - Open the new file and fill in the required information.
- Remove what is not needed.
- Run
make previewto build the docs and preview them locally. - Send a PR with "KB" in its title.
Building User Documentation
Prerequisites
- Python 3. Check your version with
$ python --version. - poetry 1.12 or later
- make
Mac OS X
You must have a working Homebrew in order to install the needed tools.
You also need the standard utility make.
Check if you have these two items with the following commands:
brew help
make -h
Linux Distributions
Building the user docs should work out of the box on most Linux distributions.
Windows
Use "Bash on Ubuntu on Windows" for the same tools and capabilities as on Linux distributions.
Building the Docs
- Run
make previewto build the documentation. - Preview the built documentation locally at http://127.0.0.1:5500/.
Cleanup
You can clean up all the build products and auto-installed Python stuff with:
make pristine
