Use the loadfroms3toredshift function to use the Redshift COPY command to copy data files from an Amazon Simple Storage Service (S3) bucket to a Redshift table. That last point is significant for achieving maximum throughput - if you have 8 nodes then you want n*8 files e.g. The number of files should be a multiple of the number of slices in your.For optimum parallelism, the ideal size is between 1 MB and 125 MB after compression. ![]()
