Real-time Analytics

🍃 MongoDB Real-time Analytics

Native Change Streams: MongoDB's built-in change detection enables sub-second analytics by streaming data changes directly to your analytics pipeline. No external infrastructure required for real-time processing.

Implementation: Use Change Streams to trigger instant analytics on data modifications, combined with the Aggregation Framework for complex real-time computations without ETL overhead.
  • Built-in Change Streams for instant notifications
  • Aggregation Framework for complex analytics
  • Sub-second latency for real-time dashboards
  • Single platform for OLTP and OLAP workloads
  • Dynamic schema handles evolving analytics needs
  • No external ETL or streaming infrastructure
Setup Complexity:
Low

🐘 PostgreSQL Real-time Analytics

External Streaming Required: PostgreSQL requires external tools like Kafka or Debezium for change detection and streaming. Analytics workloads often need separate OLAP systems like Clickhouse or external data warehouses.

Implementation: Set up logical replication, configure external streaming infrastructure, design ETL processes, and manage separate analytics databases for complex real-time workloads.
  • Logical replication for change capture
  • External tools required (Kafka, Debezium)
  • Separate OLAP systems for complex analytics
  • ETL processes increase latency
  • Schema changes require pipeline updates
  • Multiple systems to maintain and monitor
Setup Complexity:
High
