AWS S3 Multi-Region Replication optimization guide for Newly Uploaded Objects in Node.js Application
I'm a bit lost with I just started working with I'm a bit lost with I've searched everywhere and can't find a clear answer... I'm experiencing an scenario with AWS S3 multi-region replication where newly uploaded objects are not replicating to the target bucket in a different region. The source bucket is in `us-east-1` and the target bucket is in `us-west-2`. I've configured the replication rule to replicate all objects, and I've set the necessary IAM roles and policies accordingly. Here’s the replication configuration I applied: ```json { "Role": "arn:aws:iam::123456789012:role/my-replication-role", "Rules": [ { "Status": "Enabled", "Prefix": "", "Destination": { "Bucket": "arn:aws:s3:::my-target-bucket" } } ] } ``` In my Node.js application, I am using the AWS SDK for JavaScript v2. The upload code looks like this: ```javascript const AWS = require('aws-sdk'); const s3 = new AWS.S3(); const uploadFile = async (filePath) => { const params = { Bucket: 'my-source-bucket', Key: 'uploads/my-file.txt', Body: fs.createReadStream(filePath), }; try { await s3.upload(params).promise(); console.log('File uploaded successfully.'); } catch (behavior) { console.behavior('behavior uploading file:', behavior); } }; ``` After uploading, I checked the target bucket in `us-west-2`, but the file does not appear there. I verified that versioning is enabled on both buckets and that the IAM role has the correct permissions: `s3:ReplicateObject`, `s3:ReplicateDelete`, and `s3:ReplicateTags`. I've also confirmed that the source bucket has the appropriate replication configuration in place. When I look at the AWS S3 console, I do not see any errors listed in the replication status for the objects. However, after some initial troubleshooting, I checked the S3 event notifications and realized the replication might not be triggered for all object uploads. I have been uploading several files in quick succession and am wondering if this has anything to do with eventual consistency. Has anyone faced a similar scenario or have insights on what might be wrong? Any guidance on how to ensure that newly uploaded objects are correctly replicated to the target bucket would be greatly appreciated! Has anyone dealt with something similar? This is my first time working with Javascript LTS. Any advice would be much appreciated.
