amazon-s3

问题 I have a setup with Kinesis Firehose ingesting data, AWS Lambda performing data transformation and dropping the incoming data into an S3 bucket. The S3 structure is organized by year/month/day/hour/messages.json, so all of the actual json files I am querying are at the 'hour' level with all year, month, day directories only containing sub directories. My problem is I need to run a query to get all data for a given day. Is there an easy way to query at the 'day' directory level and return all

问题 This script requires the name of the new bucket in order to be attached. However, it would not receive the name of the new S3 bucket to be referred to in the script. What way can I obtain the name of the new bucket automatically in this script? import json # Create a bucket policy bucket_name = 'BUCKET_NAME' bucket_policy = { 'Version': '2012-10-17', 'Statement': [{ 'Sid': 'AddPerm', 'Effect': 'Allow', 'Principal': '*', 'Action': ['s3:GetObject'], 'Resource': f'arn:aws:s3:::{bucket_name}/*' }

问题 How to make sure that Process A has completely written large file (5+ GB) in AWS S3 Bucket A before Process B starts copying file to AWS S3 Bucket B using boto3? 回答1: If a new object is being created in Amazon S3, it will only appear after the upload is complete. Other processes will not be able to view it until is has finished uploading. Objects cannot be updated in S3. Rather, they are replaced with a new object. So, if an object is in the process of being updated, it will still appear as

问题 The first time I ran the query, it returned 2 rows with columns names. I edited the table and added skip.header.line.count - 1 and reran(First time), but it returned same result with double inverted commas. Then reran again(Second time), and this changed everything. First time Query run output: https://i.stack.imgur.com/k6T2O.png Second time Query run output: https://i.stack.imgur.com/6Cxrf.png 回答1: The problem is that output files from Amazon Athena are being mixed-in with your source files.

问题 I set up Jenkins , pm2 on AWS ubuntu server. I had a website A that built by jenkins . The jenkins then will start that website by pm2 in the configured shell. However, only I start the website by logging on to the ubuntu server manually and run pm2 start A can make the website running. The problem seems that pm2 started by user jenkins will not be visible by the outside world. Only started by user ubuntu (via ssh ubuntu@myubuntuserver) can be effectively public. Why and how can I make

问题 i'm currently working on file upload directly to S3. The user should have the ability to drag a file/files to a defined part of the site. Then a request to my server starts and generates signatures for the uploaded file/files At first i request valid signatures which are calculated from the server. The generated signature(s) looks like this: [ { "success_action_status":"<status>successful</status>", "formAction":"http://[mybucket].s3.amazonaws.com", "Policy":
