问题 I am dealing with potentially huge CSV files which I want to export from my Rails app, and since it runs on Heroku, my idea was to stream these CSV files directly to S3 when generating them.

问题 Heres my setup; - I have a local PC running ffmpeg with output configured to h.264 and aac - and S3 bucket created at AWS what i need to do is, use ffmpeg [local] output to upload files directly to s3 bucket. PS: Planing to use that s3 bucket with cloudfront to allow 1 [one] user to stream a live event with about setup. i could not find a way to specify output location as s3 bucket [with key]. any ideas as to how to do it?

问题 Hi I am looking for the best way to redirect / route all s3 bucket links to a domain or link domain to s3 bucket. I am migrating from dedicated hosting to aws and using s3 bucket to store files.

问题 After the ETL Job is done, What is the best way to call stored procedure in AWS Glue script? I am using PySpark to fetch the data from S3 and storing in staging table. After this process, need to call a stored procedure. This stored procedure loads data from the staging table into the appropriate MDS tables. If I have to call a Stored Procedure after ETL Job is done, what is the best way? If I consider AWS lambda, is there any way that lambda can be notified after the ETL. 回答1: You can use

问题 I would like to iterate through each s3 bucket object and use a sql expression to find all the content that match the sql. I was able to create a python script that lists all the objects inside my bucket. import boto3 s3 = boto3.resource('s3') bucket = s3.Bucket('bucketname') startAfter = 'bucketname/directory' for obj in bucket.objects.all(): print(obj.key) I was also able to create a python script that uses a sql expression to look through the object content. import boto3 S3_BUCKET =
