S3 HashAggregate和S3 Query Scan操作;同时Redshift不会执行外部表的统计信息(statistics),执行计划会提示“Tables missing statistics: spectrum_sales”,该执行计划会默认本地表的数据量要远远少于存储在S3上的外部数据量。
在Amazon Redshift当中,我们可以使用UNLOAD命令或写入外部表的方式,将数据导出至数据湖内。这两种方式都能够以并发形式将SQL语句的输出结果导入Amazon S3。具体操作步骤如下: 使用您所熟悉的CREATE EXTERNAL TABLE AS SELECT与INSERT INTOSQL语句在Amazon S3上创建并填充外部表,以供Amazon Redshift或者甚至加入数据湖的服...
Amazon Redshift Spectrum作为Amazon Redshift的特性可以允许您直接从Redshift集群中查询S3数据湖,而无需先将数据加载到其中,从而最大限度地缩短了洞察数据价值时间。 Redshift Spectrum支持Lake house架构,可以跨Redshift、Lake house和操作数据库查询数据,而无需进行ETL或加载数据。Redshift Spectrum支持开放数据格式,如P...
