refactor: single RC subscriber by P403n1x87 · Pull Request #16299 · DataDog/dd-trace-py

P403n1x87 · 2026-02-02T11:18:04Z

Description

This PR refactors the Remote Configuration (RC) architecture from a multiple-subscriber model (one thread per product) to a single-subscriber model with product dispatching. This reduces thread overhead and simplifies the RC polling infrastructure.

Key Changes

Architectural Simplification

Before: Each product registered its own subscriber thread
After: Single global subscriber dispatches payloads to registered product callbacks
Benefit: Reduced thread count improves resource efficiency and simplifies lifecycle management

New RCCallback Interface

Products now register callbacks by implementing the RCCallback abstract base class:

from ddtrace.internal.remoteconfig import RCCallback, Payload
from typing import Sequence

class MyProductCallback(RCCallback):
    def __call__(self, payloads: Sequence[Payload]) -> None:
        """Process configuration payloads when received."""
        for payload in payloads:
            # Process configuration updates
            ...
    
    def periodic(self) -> None:
        """Optional: Perform periodic operations at every polling cycle."""
        # Emit metrics, check stale state, etc.
        pass

Key features:

__call__(payloads): Abstract method called when configuration updates are received
periodic(): Optional method called at every polling interval (before payload processing), regardless of whether new configuration was received
Enables time-based operations like probe status emission, stale request cleanup, and periodic metrics

Registration Pattern

from ddtrace.internal.remoteconfig.worker import remoteconfig_poller

callback = MyProductCallback()
remoteconfig_poller.register(
    product="MY_PRODUCT",
    callback=callback,
    capabilities=[...]
)

The single subscriber calls:

callback.periodic() for all registered callbacks at every poll cycle
callback(payloads) when new configuration is available for that product

Benefits

Reduced thread overhead: One subscriber thread instead of N threads (one per product)
Cleaner separation: Periodic operations separated from payload processing logic
Better testability: Callbacks can test periodic() independently of payload handling
Consistent interface: All products follow the same registration pattern

Migration Notes

Existing callbacks automatically get no-op periodic() behavior. No breaking changes for products that don't need periodic operations.

Additional Notes

Claude Code made the largest chunk of the changes. It has been guided step-by-step to perform the following tasks

Move to a single subscriber design whereby a single subscriber thread runs in each process. It then dispatches configurations to the appropriate callbacks.
Use the smaller RCCallback for registering product RC callbacks and remove most of the PubSub boilerplate code into the single subscriber.

Specific changes in appsec

remove the appsec preprocessing part, as it's not required anymore to be outside of the usual appsec callback
update the tests accordingly

the appsec RC layer is tested extensively on the system tests
