Description

See PR title.

By refactor, we mean two things:

  1. The MariaDB/MySQL setup section now covers only database-server setup. We moved the CLP database/user creation steps to a new section called Using an external database with CLP.
  2. In the new section Using an external database with CLP, we now provide instructions for configuring both Helm chart values and Docker Compose (whereas previously, it only covered Docker Compose)..

We also added a new section called Using an external database with Spider to document the Spider external database setup. This section includes how a user can reuse the CLP database/user creation steps and how to configure it for a Kubernetes setup using Helm values. Since Spider does not support external database configuration in Docker Compose, we do not mention Docker Compose there.

We also adds the description for configuration spider.spiderConfig.database in "Using Spider Scheduler" user guide to make it complete.

Walkthrough

The documentation now covers external database setup for Docker Compose, Helm, and Spider deployments. It adds MariaDB/MySQL prerequisites, shared setup procedures, deployment settings, credentials, and Spider database configuration guidance. The development utility submodule reference also changed.

Changes

External database guide

Layer / File(s) Summary
Database prerequisites and AWS RDS
docs/src/user-docs/guides-external-database.md
The guide updates MariaDB and MySQL prerequisites, remote connections, AWS RDS setup, and MongoDB verification instructions.
Docker Compose configuration
docs/src/user-docs/guides-external-database.md
The guide adds shared CLP database and user setup, privilege grants, connection verification, external database settings, and otel_collector to the bundled-service example.
Helm and Spider configuration
docs/src/user-docs/guides-external-database.md, docs/src/user-docs/guides-using-spider-scheduler.md
The documentation adds Helm values for external databases and credentials, Spider’s external MariaDB setup, the spider.spiderConfig.database setting, a Kubernetes deployment reference, and removes the obsolete multi-host reference.

Development utility reference

Layer / File(s) Summary
Utility submodule update
tools/yscope-dev-utils
The submodule reference now points to commit 6ec46856cfda8cbfb65d9386affbe3bc429186cb.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk: 🟠 High · up to c059e

The guide currently contains examples that can connect to the wrong database, fail Spider deployment, expose database credentials broadly, or incorrectly deny supported deployment options. These issues should be corrected before merging because they can cause failed or insecure user deployments.

200-218: 🔒 Security & Privacy | 🟡 Minor | ⚡ Quick win

Add MongoDB authentication and TLS configuration, or remove the recommendation. ResultsCache supports only host, port, db_name, stream_collection_name, and retention_period, and it always builds mongodb://host:port/db_name. The Docker Compose and Helm examples therefore cannot configure MongoDB credentials or TLS.

- Around line 65-71: Update the external database guide’s RDS setup and
connection examples to use the configured database port and selected username
consistently, including the inbound security-group rule, the mysql command near
the RDS instructions, and the verification commands around the later connection
example. Define the chosen username and port before using them, and include the
port option in every relevant command instead of hardcoding 3306 or assuming
admin.
- Around line 141-145: Update the MariaDB setup procedure and the Spider
subsection so readers connect to the target database server before running SQL,
using the documented host/endpoint, port, and user connection details or
explicitly stating that an existing session must remain active; replace the
local socket-only sudo mysql step and add the missing connection guidance before
the Spider SQL steps.
- Around line 153-169: Update the executable MariaDB examples around the CLP and
Spider setup to use caller-specific hosts instead of granting clp-user access
from “%”. Define separate restricted accounts where CLP and Spider run on
different hosts, or otherwise use each caller’s specific allowed hostname or IP;
retain “%” only when explicitly justified by network controls. Update the
accompanying note so restricted hosts are the default rather than an optional
improvement.

Complete the dedicated Spider-user workflow.

When Spider uses another database server, the text tells the reader to create a dedicated user, but the only grant shown still targets 'clp-user'@'%'. Following this branch literally leaves the dedicated user without privileges on spider-db, so Spider cannot connect. Add the grant for the dedicated Spider user and use the same username and password in spiderConfig.database.

Proposed correction
- Otherwise, create a dedicated user first, following the same steps as in
- [Using an external database with CLP](`#using-an-external-database-with-clp`).
+ Otherwise, create a dedicated Spider user on this database server and grant
+ that user privileges on `spider-db`.

-         username: "clp-user"
-         password: "<your-mariadb-password>"
+         username: "<spider-username>"
+         password: "<spider-password>"

Document database.type in the Docker Compose configuration.

database.type defaults to "mariadb" and selects the database connector and SQLAlchemy dialect. Add the field and state that MySQL deployments must set it to "mysql".

Limit this note to external database support.

Line 29 states that Spider is not supported in Docker Compose. Spider Docker Compose deployment support was added in PR #2479, merged on August 21, 2026. (github.com)

The PR scope excludes external database configuration for Spider in Docker Compose. It does not exclude Spider Docker Compose deployment. Update this note to state the correct limitation.

Proposed wording
 :::{note}
-Spider is not supported in Docker Compose deployments in the current release. Support for Docker
-Compose is planned for a future release.
+Spider is supported in Docker Compose deployments in the current release. External database
+configuration for Spider is supported only in Kubernetes deployments.
