Question

why do we need AWS Glacier Select

Answer 1

Amazon Glacier Select allows queries to run directly on data stored in Amazon Glacier without having to retreive the entire archive. Amazon Glacier Select changes the value of archive storage by allowing you to process and find only the bytes you need out of the archive to use for analytics.

Now, your analytics application can call the Amazon Glacier Select API to retrieve only the relevant data for your query from the Amazon Glacier archive. Amazon Glacier Select will soon integrate with Amazon Athena and Amazon Redshift Spectrum so you can now consider Glacier archives a part of your data lake.

Prior to Glacier Select, an Amazon Glacier archive had to be completely restored before the data could be used. Now customers can use Glacier Select to lower their costs and uncover more insights from their archive data.
