Utiliser la projection de partition

L'exemple suivant montre une instruction CREATE TABLE pour les journaux de requête Resolver qui utilise la projection de partition et est partitionnée par VPC et par date. Pour plus d'informations sur la projection de partition, voir Utilisation de la projection de partition avec Amazon Athena.

CREATE EXTERNAL TABLE r53_rlogs (
  version string,
  account_id string,
  region string,
