Yuan Teoh 293c1d6889 feat!: update configuration file v2 (#2369)
This PR introduces a significant update to the Toolbox configuration
file format, which is one of the primary **breaking changes** required
for the implementation of the Advanced Control Plane.

# Summary of Changes
The configuration schema has been updated to enforce resource isolation
and facilitate atomic, incremental updates.
* Resource Isolation: Resource definitions are now separated into
individual blocks, using a distinct structure for each resource type
(Source, Tool, Toolset, etc.). This improves readability, management,
and auditing of configuration files.
* Field Name Modification: Internal field names have been modified to
align with declarative methodologies. Specifically, the configuration
now separates kind (general resource type, e.g., Source) from type
(specific implementation, e.g., Postgres).

# User Impact
Existing tools.yaml configuration files are now in an outdated format.
Users must eventually update their files to the new YAML format.

# Mitigation & Compatibility
Backward compatibility is maintained during this transition to ensure no
immediate user action is required for existing files.
* Immediate Backward Compatibility: The source code includes a
pre-processing layer that automatically detects outdated configuration
files (v1 format) and converts them to the new v2 format under the hood.
* [COMING SOON] Migration Support: The new toolbox migrate subcommand
will be introduced to allow users to automatically convert their old
configuration files to the latest format.

# Example
Example for config file v2:
```
kind: sources
name: my-pg-instance
type: cloud-sql-postgres
project: my-project
region: my-region
instance: my-instance
database: my_db
user: my_user
password: my_pass
---
kind: authServices
name: my-google-auth
type: google
clientId: testing-id
---
kind: tools
name: example_tool
type: postgres-sql
source: my-pg-instance
description: some description
statement: SELECT * FROM SQL_STATEMENT;
parameters:
- name: country
  type: string
  description: some description
---
kind: tools
name: example_tool_2
type: postgres-sql
source: my-pg-instance
description: returning the number one
statement: SELECT 1;
---
kind: toolsets
name: example_toolset
tools:
- example_tool
```

{{< notice note >}} ⚠️ Best Effort Maintenance

This integration is maintained on a best-effort basis by the project team/community. While we strive to address issues and provide workarounds when resources are available, there are no guaranteed response times or code fixes.

The automated integration tests for this module are currently non-functional or failing. {{< /notice >}}

About

A dgraph-dql tool executes a pre-defined DQL statement against a Dgraph database. It's compatible with any of the following sources:

To run a statement as a query, you need to set the config isQuery=true. For upserts or mutations, set isQuery=false. You can also configure timeout for a query.

Note: This tool uses parameterized queries to prevent SQL injections. Query parameters can be used as substitutes for arbitrary expressions. Parameters cannot be used as substitutes for identifiers, column names, table names, or other parts of the query.

Example

{{< tabpane persist="header" >}} {{< tab header="Query" lang="yaml" >}}

kind: tools name: search_user type: dgraph-dql source: my-dgraph-source statement: | query all($role: string){ users(func: has(name)) @filter(eq(role, $role) AND ge(age, 30) AND le(age, 50)) { uid name email role age } } isQuery: true timeout: 20s description: | Use this tool to retrieve the details of users who are admins and are between 30 and 50 years old. The query returns the user's name, email, role, and age. This can be helpful when you want to fetch admin users within a specific age range. Example: Fetch admins aged between 30 and 50: [ { "name": "Alice", "role": "admin", "age": 35 }, { "name": "Bob", "role": "admin", "age": 45 } ] parameters:

  • name: $role type: string description: admin

{{< /tab >}} {{< tab header="Mutation" lang="yaml" >}}

kind: tools name: dgraph-manage-user-instance type: dgraph-dql source: my-dgraph-source isQuery: false statement: | { set { _:user1 $user1 . _:user1 $email1 . _:user1 "admin" . _:user1 "35" .

    _:user2 <name> $user2 .
    _:user2 <email> $email2 .
    _:user2 <role> "admin" .
    _:user2 <age> "45" .
    }
   }

description: | Use this tool to insert or update user data into the Dgraph database. The mutation adds or updates user details like name, email, role, and age. Example: Add users Alice and Bob as admins with specific ages. parameters:

  • name: user1 type: string description: Alice
  • name: email1 type: string description: alice@email.com
  • name: user2 type: string description: Bob
  • name: email2 type: string description: bob@email.com
