Some COPY FROM options are not available for all file types.
See Required Permissions in Creating External Tables. For most external tables, you must also define a user storage location to allow non-administrative users to query the table. We open Amazon S3 and select one bucket from the list, on which we want to enable automatic deletion of files after a specified time.When using COPY in conjunction with a CREATE EXTERNAL TABLE statement, you cannot use the COPY FROM STDIN or LOCAL options. On the AWS (Amazon Web Service) platform, we can easily automatically delete data from our S3 bucket. If you have any data in AWS that you would like to automatically delete after a certain period of time, then this article is for you !! Automatic deletion of data from the entire S3 bucket For some systems it will be 30 days, for others it will be 90 days, and for some systems it will be a year or several years, if we are required to do so by law and regulations. L et’s not keep data longer than we have to. Storing them is also cheap and convenient, only … only logs also have validity. The same applies to logs stored in the cloud. With the stubbornness of a maniac, we collect the necessary data, keep it, and after some time it becomes unnecessary and obsolete. If we don’t, we’ll be drowned in a flood of information.
Nowadays, we need to filter the data well to find something that is useful to us. Why?īecause it is cheap, convenient and we have access to it from anywhere in the world 🙂 What about the cloud? Since the price for storage has become very low, many of us collect data not only at home, but in the cloud. Some people view their datasets and periodically delete unnecessary things. Unfortunately, a very large part of the data we collect is unnecessary or out of date after some time. Fast internet and data availability support this very much. We usually store a lot of files during our work.
