Copy data from Redshift To MySQL/PSQL

Question

I tried searching for it but couldn't find out...

What is the best way to copy data from Amazon Redshift to MySQL/PSQL Database ?

Only solution I know of is to copy data from Redshift to my machine and then move it to MySQL/PSQL but that of course, is I/O intensive and not scalable.

Can anyone please suggest something better (may be something via S3) ?

Answer 1

There are many ways you can do that:

1. Use UNLOAD command of Redshift to export and upload table data into S3. Then import them into your psql/ MySQL tables using the AWS S3 SDK(maybe using Python/ Java)

2. Use AWS Data Pipeline to create dataflows to export Redshift data and import them into your choice of databases

3. Use AWS SDKs to programmatically export Redshift data using Python/ Java/ Ruby and import the data back into your databases.

Answer 2

This is exactly what AWS Data Pipeline is built for. Please have a look at our working sample for accomplishing what you want to do:
