Default Filters Configuration for Query Builder

[kakao-phil-lsp]

Problem

In multi-tenant environments, users often need to apply the same filters (e.g., tenant_id, env) to every query. Currently, this requires manually adding filters each time, which is repetitive and error-prone.

Proposed Solution

Add a Default Filters section in datasource settings. Filters configured here would automatically populate in the query builder when creating new queries.

Example YAML provisioning:

jsonData:
  logs:
    defaultFilters:
      - key: env
        operator: Equals
        value: production

Behavior:

• Applies to Logs, Traces, TimeSeries, and Table query types
• Users can modify/remove filters per query
• Existing queries remain unaffected

Use Case

Multi-tenant platform where each team should only query their own data:

• Configure tenant_id = 'team-a' as default filter
• All new queries automatically include this filter
