Hi @Hubert Dudek​ and @47kappal​ ,

Sorry for the delay. As suggested I'm trying to setup a gateway endpoint for s3 following https://docs.aws.amazon.com/vpc/latest/privatelink/vpc-endpoints-s3.html

I am a bit confused by

A gateway endpoint is available only in the Region where you created it. Be sure to create your gateway endpoint in the same Region as your S3 buckets.

In my case the vpc used by the cluster (and in which the gateway will be created) is us-east-1 while s3 bucket is in eu-west-1 so above statement can't be respected (bucket and gateway won't be in same region)

I am also confused by the fact that iw works with format(csv) but not with format(s3select). I wonder about limitations with s3 select connector.
