I had following questions:

1. Are we allowed to attach multiple data-source of same type like S3 on an instance of Dremio ?
2. If yes, is there any limit on the number of adding s3 as a data-source to the same instance of Dremio ?

Thanks in advance

Yes, you can have multiple of the same data source (e.g. multiple s3 buckets). There is no hard limit on the number of sources, but keep in mind that there can be performance issues when it starts to get into the several hundreds.
