I am doing a POC on Airbyte hosted in EC2 instance, with RDS(Postgres) as source and Redshift as destination. Now while configuring destination, using uploading method as "S3 staging" is it possible to configure without "S3 Key Id" and "S3 Access Key"? (Similar to S3 as destination)

Based on the information provided in the extracts, it appears that both the "Access Key ID" and "Secret Access Key" are required fields when setting up S3 as a staging area for the Redshift destination in Airbyte. This is mentioned in the extracts from the [Redshift destination setup guide](https://docs.airbyte.com/integrations/destinations/redshift) and the [S3 destination setup guide](https://docs.airbyte.com/integrations/destinations/s3). For the Redshift destination, when using the COPY strategy (which involves staging data in an S3 bucket), you need to provide the "Access Key ID" and "Secret Access Key". These credentials are used to authenticate with AWS and grant Airbyte the necessary permissions to write data to the S3 bucket. Similarly, for the S3 destination, you need to provide the "Access Key ID" and "Secret Access Key" to allow Airbyte to read and write data to the S3 bucket. Therefore, it seems that you cannot configure the S3 staging area for the Redshift destination without providing the "Access Key ID" and "Secret Access Key".
