MongoDB IoT Pipeline Architecture

IoT Data Pipeline Architecture Comparison

High-Throughput Sensor Data Processing

Compare how MongoDB and PostgreSQL handle IoT data pipelines, examining time-series optimization, throughput capabilities, and real-time analytics support.

🔍 Key IoT Architecture Differences

MongoDB's native time-series collections are purpose-built for sensor data, while PostgreSQL requires extensions and additional tools to achieve similar IoT data processing capabilities.

🍃 MongoDB IoT Data Pipeline

Native Time-Series Collections: MongoDB provides purpose-built collections optimized for sensor data with automatic compression, bucketing, and efficient time-based queries.

Time-Series Optimization: Native collections designed for sensor data
Automatic Compression: Up to 93% storage reduction for historical data
High Throughput: Handle millions of data points per second
Flexible Schema: Accommodate varying sensor data structures
Built-in Analytics: Aggregation pipelines for real-time insights

Purpose-Built

Native time-series support without extensions

🐘 PostgreSQL IoT Data Pipeline

Extension-Based Time-Series: PostgreSQL requires TimescaleDB or similar extensions, along with external tools for high-throughput IoT data processing and analytics.

SQL Analytics: Complex time-series queries with SQL
ACID Compliance: Strong consistency for sensor data
Mature Tooling: Rich ecosystem for monitoring and analysis
Compression: Available through extensions
Relational Integrity: Foreign key constraints for metadata
