SurveyCTO to Amazon S3 Data Lake Integration
AI-first ETL from SurveyCTO into Amazon S3 Data Lake. Governed entities, incremental sync, typed landing tables.
How Datrise loads SurveyCTO into Amazon S3 Data Lake
Datrise syncs SurveyCTO's form submissions, forms, fields, answers, enumerators, and submission timestamps into Amazon S3 Data Lake as columnar Parquet objects partitioned per source entity. Flexible or custom fields land in nested struct/map fields in Parquet, and timestamps such as created, updated, and status changes are typed as ISO-8601 timestamp columns.
Sync is incremental: Datrise uses writes new date partitions and compacts small files on a schedule, so re-runs update only what changed. Hive-style path partitioning (entity/date) for engine-agnostic reads. A lake has no schema enforcement, so Datrise writes a schema manifest alongside the data to keep downstream engines consistent.
Ideal for an open, engine-neutral storage layer for Spark, Athena, Trino, or DuckDB.
