About this blueprint
AWS Ingest S3 SQL
This flow will:
- Query data from a Druid server
- Convert the result to a CSV file
- Upload the CSV file to S3
- Create a table in Redshift if it does not exist
- Insert data from the CSV file into the Redshift table.
To set up Apache Druid locally, follow the instructions mentioned in the official documentation. The example Druid dataset wikipedia has been used in this flow.
