Architecture

Notion’s core production architecture is centered on a sharded PostgreSQL system on AWS, with 96 physical Postgres instances and five logical shards per instance as of 2023. Its data lake pipeline uses Debezium CDC into Confluent Cloud Kafka, then Apache Hudi and S3 for downstream analytics, search, and AI-related workloads; the public sources do not confirm a native foundational model inside Notion’s core product.
