Tableau Connector for Amazon Athena

Build 21.0.7929

CleanQueryResults

Amazon Athena produces cache files with every query, in the folder specified in S3StagingDirectory . CleanQueryResults specifies whether these files should be deleted once the connection is closed.

Data Type

bool

Default Value

true

Remarks

Amazon Athena stores the results of every query you execute as a CSV file in S3StagingDirectory. These CSV files can quickly rack up a lot of space in Amazon S3.

You can use CleanQueryResults, enabled by default, to clean these files for every query executed. Note that this behavior will add a minor performance hit when you disconnect the last connection in a process.
