chore(django): make minimal tracing the default #15216

brettlangdon · 2025-11-11T21:11:33Z

Description

This change updates the default Django instrumentation experience to use DD_DJANGO_TRACING_MINIMAL=true.

While this is a significant shift, it simplifies the default tracing behavior and improves performance by removing redundant spans.

Summary of Changes

1. Remove default instrumentation for Django ORM, cache, and template layers

Previously, Django’s database, cache, and template operations were instrumented even when their underlying libraries (e.g., psycopg, mysql, redis, memcached, jinja2) were already instrumented.
This resulted in duplicate spans for each operation, with nearly identical metadata.

Originally, these Django-level spans were added as a safeguard—ensuring coverage even if the underlying libraries weren’t instrumented. However, this extra layer now adds measurable overhead and no longer provides meaningful value in most cases.

To restore the previous behavior, you can either:

Set DD_DJANGO_TRACING_MINIMAL=false
Or selectively enable instrumentation:
- DD_DJANGO_INSTRUMENT_DATABASES=true
- DD_DJANGO_INSTRUMENT_CACHES=true
- DD_DJANGO_INSTRUMENT_TEMPLATES=true

2. Adjusted behavior when `DD_DJANGO_INSTRUMENT_DATABASES=true`

When database instrumentation is enabled, Django will now merge its database spans into those from the underlying driver (psycopg, mysql, sqlite3, etc.) if one is detected.
A standalone Django span will only be created if:

The underlying driver is not instrumented, or
Its instrumentation cannot be detected.

This ensures that enabling Django database instrumentation no longer produces redundant spans and maintains consistent behavior across drivers.

Motivation

This change reduces tracing overhead, improves clarity in trace visualizations, and improves the default performance overhead experienced when tracing Django applications.
