Athena Query Using Partition at Emma Joanne blog

Athena Query Using Partition. Store your data as a partition in amazon simple storage service (amazon s3). Athena has added support for partition projection, a new functionality that you can use to speed up query processing of highly. It increases the query response time as well as a reduction in cost. Let's say i want to have partitions by some attribute and in each partition i have couple of files with records in json (each file has more. Partition projection helps minimize this overhead by allowing you to query partitions by calculating partition information rather than retrieving it from a metastore. You can use partition projection in athena to speed up query processing of highly partitioned tables and automate partition. Using the partition, athena can scan the data in the relevant partition, reducing the amount of data scanned. You can use partition projection in athena to speed up query processing of highly partitioned tables and automate partition management. Partitioning and bucketing are two ways to reduce the amount of data athena must scan when you run a query. To create a partitioned athena table, complete the following steps:
