In this post, we walk through the process of exporting data from a DynamoDB table to Amazon Redshift. We discuss data model design for both NoSQL databases and SQL data warehouses. We begin with a single-table design as an initial state and build a scalable batch ...
基于Glue构建的数据加载pipeline中,我们同样可以利用SQL执行ETL将变更数据更新至Redshift中。 post_query="begin;delete from target_table using stage_table where stage_table.id = target_table.id ; insert into target_table select * from stage_table; drop table stage_table; end;"datasink4=glueContext...
