Amazon DynamoDB to Amazon Athena Integration
AI-first ETL from Amazon DynamoDB into Amazon Athena. Governed entities, incremental sync, typed landing tables.
How Datrise loads Amazon DynamoDB into Amazon Athena
Datrise syncs Amazon DynamoDB's tables, items, partition keys, sort keys, attributes, and stream records into Amazon Athena as partitioned Parquet in S3 exposed as an Athena table. Flexible or custom fields land in struct/map columns in Parquet, and timestamps such as created, updated, and status changes are typed as timestamp.
Sync is incremental: Datrise uses writes new Parquet partitions and registers them in the Glue Data Catalog, so re-runs update only what changed. Hive-style partitioning by load date so Athena scans only new data. Athena bills per byte scanned and small files hurt, so Datrise compacts to right-sized Parquet rather than many tiny objects.
Ideal for serverless SQL over an S3 lake without a running warehouse.

How Amazon DynamoDB entities map to Amazon Athena
| Amazon DynamoDB entity | Amazon Athena object | Notes |
|---|---|---|
| tables | source_dynamodb_tables | id PK · custom fields → struct/map columns in Parquet |
| items | source_dynamodb_items | id PK · linked to source_dynamodb_tables |
| partition keys | source_dynamodb_partition_keys | id PK · linked to source_dynamodb_tables |
| sort keys | source_dynamodb_sort_keys | id PK · linked to source_dynamodb_tables |
FAQ
How does Datrise handle Amazon DynamoDB's custom fields in Amazon Athena?
Flexible values are stored as struct/map columns in Parquet, so new fields don't require a migration; strongly-typed fields — dates, numbers, and references — are promoted to native Amazon Athena types.
How does the Amazon DynamoDB to Amazon Athena sync stay up to date?
It runs incrementally — Datrise uses writes new Parquet partitions and registers them in the Glue Data Catalog.
