这个简单的介绍并不能使你全面了解
Athena
,但可以让你了解到
Presto
在行业内的应用情
况,以及
Presto
与其他产品的区别。
使用
Athena
可
以满足不同的需求,但有一些特定的限制和特性。例如,
Athena
对较大的、
运行时间较长的查询施加了限制。
因为你是为处理后的数据量而不是运行软件的基础设施付费,所以成本计算也有很大不同。
每次运行查询时,你都要为处理的数据付费。根据你的使用模式,这可能更便宜,也可能
更贵。具体来说,为了降低查询成本,你可以在
S3
中预处理数据
,从而使用
Parquet
和
ORC
等格式并进行压缩。当然,预处理也是有代价的,因此你必须去尝试优化整体成本。
许多其他平台以类似的、隐蔽的方式使用
Presto
,从而为用户和这些平台的提供者提供了
强大的能力。如果你追求管控力和灵活性,运行自己部署的
Presto
仍是一个很棒的选择。
