Anusha Challa, et al, announce a new version of a Redshift query editor:
Amazon Redshift is a fast, fully managed, petabyte-scale cloud data warehouse. You have the flexibility to choose from provisioned and serverless compute modes. You can start loading and querying large datasets conveniently in Amazon Redshift using Amazon Redshift Query Editor v2, a web-based SQL client application.
It’s worth a try if you’re a Redshift user, though I’d imagine that frequent Redshift users have already sorted out their IDEs of choice.
