Workflow

COS S3 Select feature enables applications to filter and retrieve only a subset of data from an object by using simple SQL-like expressions. To accomplish this the user will send an HTTP POST request against the Object Resource using the query parameters “select” and “select-type”. The SQL query and the input and output serialization formats are defined in the SelectObjectContent XML body of the POST request. Please refer to the CSO API guide for more information and examples.
