# Loading Data From DynamoDB Into Amazon Redshift

DynamoDB is an exceptional key-value store with great performance characteristics. But it's quite limited when it comes to data analysis and business intelligence queries.

Before you can copy data from a DynamoDB table, you need to create the corresponding table in Redshift.

The following copy command performs the copy (this will count against your DynamoDB's read capacity):

copy users from 'dynamodb://my-users'
credentials 'aws_access_key_id=<Your-Access-Key-ID>;aws_secret_access_key=<Your-Secret-Access-Key>'

where users is the destination table in Redshift, my-users is the corresponding DynamoDB table and readratio is how much of the provisioned read capacity the copy operation can consume.
2. The DynamoDB attributes are case-insensitively matched to the Redshift table's columns. If there are two columns on Redshift that can match case-insensitively to the DynamoDB attributes, the copy command will fail.
3. The data types on Redshift and Dynamo do not match one-to-one. For example, DynamoDB's binary and set data types are not supported.
