2. False



Correct Answer : Get Lastest Questions and Answer :

Explanation: Amazon S3 maintains an index of object key names in each AWS region. Object keys are stored lexicographically across multiple partitions in the index. That is, Amazon S3 stores key names in alphabetical order. The key name dictates which partition the key is stored in. Using a sequential prefix, such as timestamp or an alphabetical sequence, increases the likelihood that Amazon S3 will target a specific partition for a large number of your keys, overwhelming the I/O capacity of the partition. If you introduce some randomness in your key name prefixes, the key names, and therefore the I/O load, will be distributed across more than one partition.




Question : Since S object are stored lexicographically, by introducing "randomness" to your S names it helps S storage distribute
the I/O load across more than one partition. Given the following examples, how could you add a hashed prefix to the naming
convention to increase I/O performance? bucket/2010-26-05-15-00-00/myfolder234234/photo1.jpg bucket/2010-26-05-15-00-00/myfolder3857422/photo2.jpg
