UNLOAD Redshift: append
问题 I'd like to UNLOAD data from Redshift table into already existing S3 folder, in a similar way of what happens in Spark with the write option " append " (so creating new files in the target folder if this already exists). I'm aware of the ALLOWOVERWRITE option but this deletes the already existing folder. Is it something supported in Redshift? If not, what approach is recommended? (it would be anyway a desired feature I believe...) 回答1: One solution that could solve the issue is to attach
