Amazon Athena updates data source connectors to improve performance and reduce cost

Amazon Athena has updated its data source connectors with new optimizations that can improve performance and reduce cost when querying data that does not reside in Amazon S3. Available today, the updated connectors use dynamic filtering and new predicate push down optimizations to perform more operations in the underlying data source, rather than in Athena, which can reduce query processing time and reduce data scanned.
