在特定帐户中创建s3存储桶并使用JAVA将对象放入其中的最佳实践？

Question

I am doing a project where I have to measure reliability of a service. I have a Producer/Consumer setup to do that. In my consumer side I am receiving events and each event has a unique eventID. As I have all the eventID's for the events which are published by the producer. My approach is to write all the eventID's for the events received at consumer side and write it to a s3 bucket. I found this example here but I have few doubts so here are my questions:

1- How does my java code will know in which AWS account it needs to create a s3 Bucket?

2- I want to write data for a day and save it everyday, so how to do that?

Let me know if you need any other information from my side?

Answer 1

1- How does my java code will know in which AWS account it needs to create a s3 Bucket?

Have a look at the documentation and see the implementation classes. They all provide different options how the account credentials can be specified.

The ProfileCredentialsProvider will use the profile configuation in ~/.aws/credentials file

2- I want to write data for a day and save it everyday, so how to do that?

I am not sure what you want from the description, here I will assume you want to gather events for a whole day and write the whole set into the S3 bucket (do not create butckets dynamically, number of buckets is limited)

you cannot update an S3 object. So using pure S3 you could eg create a folder (s3 key prefix) for each day and and store each event as an object

If you want to have an aggregated list for each day, you will need to store data somewhere else for the day (eg DynamoDB, CloudWatch,..) and export logs into the S3 object daily (eg for DynamoDB you could create a Data Pipeline or a Lambda function to export data into an S3 bucket)
