The Business Problem

Operational & Architectural Constraints

A marketing technology platform needed to consolidate advertising performance and attribution data across multiple niche ad networks and regional marketing platforms. Off-the-shelf Airbyte connectors were either unavailable or did not support custom reporting endpoints, dynamic metric breakdowns, or strict API pagination constraints, resulting in broken extraction scripts and data gaps.

Our Engineering Approach

System Design & Implementation

We engineered custom source connectors adhering to the Airbyte Python Connector Development Kit (CDK). The connectors implemented dynamic stream generation based on advertiser account configurations, cursor-based and offset pagination strategies, and intelligent backoff algorithms handling HTTP 429 throttling. Each connector was packaged into a hardened Docker container, integrated into Airbyte's declarative catalog, and validated against API rate-limit stress tests.

End-to-End System Data Flow

ARCHITECTURE_SPEC // CONNECTOR

System Data Flow: Custom Airbyte Advertising Data Connectors

The Airbyte orchestrator triggers the containerized custom source connector, which authenticates, reads incremental cursor state, queries paginated ad endpoints, and emits standardized AirbyteRecordMessage streams.

STEP 01 ACTIVE TELEMETRY // Airbyte Worker & Config[TRANSACTION_COMMITTED]

Instantiates connector container passing encrypted credentials, stream selection, and prior state cursor.

Engineered via: Airbyte OSS Engine
Data Integrity & Isolation

Strict tenant isolation and atomic data boundaries enforced at both gateway validation and persistence/table tiers.

Telemetry & Observability

Every stage emits structured trace contexts (OpenTelemetry / correlation IDs) for distributed debugging and latency profiling.

Technical Tradeoffs

Key Engineering Decisions

DECISION_01

Python CDK over low-level raw protocol implementation

Technical Rationale:

Accelerated development by leveraging native CDK primitives for pagination, backoff, and state checkpointing.

Acknowledged Tradeoff:

Slightly higher container memory footprint compared to a compiled Go implementation, balanced by high maintainability.

DECISION_02

Incremental cursor tracking on report updated_at timestamps

Technical Rationale:

Reduced daily extraction volume by over 85% compared to full-refresh snapshots while capturing retrospective ad conversions.

Acknowledged Tradeoff:

Implemented a rolling 7-day lookback window to account for delayed attribution data updates by ad networks.

Verified Technical Outcomes
