Organizing objects using prefixes 回到顶部 2.s3性能 Amazon S3 是一个非常大的分布式系统,在应用程序对 Amazon S3 读写数据时,您可以将请求性能扩展到每秒数千个事务。 Amazon S3 性能不是按存储桶定义的,而是按存储桶中的前缀。在一个存储桶中,对于每个前缀,应用程序每秒可以处理至少 3500 个 PUT/COPY/POST/...
虽然每个人都说 s3 中没有目录和文件,只有对象(和存储桶),这是绝对正确的,但我建议利用 此 答案中描述的 CommonPrefixes。因此,您可以执行以下操作以获取“文件夹”(commonPrefixes)和“文件”(objectSummaries)的列表: ListObjectsV2Request req = new ListObjectsV2Request().withBucketName(bucket.getName()).wit...
If you specify a delimiter in the request, then the result returns each distinct key prefix containing the delimiter in aCommonPrefixeselement. The distinct key prefixes are returned in thePrefixchild element. Returns: (Array<Types::CommonPrefix>)— ...

Adjust the number of concurrent Amazon S3 requests To adjust the number of Amazon S3 requests to have fewer concurrent reads per prefix, you can configure Spark parameters. By default, Spark populates 10,000 tasks to list prefixes when creating Spark DataFrames. ...
