Process to create Pre-signed URL

[mahimatics]

AWS SDK Exploration

• [x] Figure out how to use the AWS SDK for Java with credentials (maybe without the IAM stuff to begin with)- https://docs.aws.amazon.com/AmazonS3/latest/userguide/example_s3_Scenario_PresignedUrl_section.html
  • [x] https://docs.aws.amazon.com/sdkref/latest/guide/jvm-system-properties.html
  • [ ] https://docs.aws.amazon.com/sdkref/latest/guide/feature-static-credentials.html
• [x] Try to list data in the bucket - https://www.baeldung.com/java-aws-s3-list-bucket-objects
• [x] Try to create a pre-signed URL (for uploading data, PUT)
• [x] Try to upload some data using the pre-signed URL

Process Code

To start

• Inputs
  • Bucket name
  • Key name (name under which the file gets uploaded into S3)
• Based on input, create the URL and end process
• Keep this process as async
  • executeBlocking may not be needed for this process

    Make the process sync

• Check feasibility

[mahimatics]

• [ ] Need to explore either creating /results or sync process
• [ ] Change process input to accept bucket, region, rID
• [ ] Check the expiration time

[ThorodanBrom]

• Given resource ID
  • Ownership
  • Get the name of the resource and resourceGroup ID as well
  • Call item API again with the resourceGroup and get the name
  • New object key name will be RG-name/RI-name.extension
• Check if the key already exists - using HEAD
• New input called fileType
  • GeoPackage - .gpkg

Size testing yet to be done. Sync process code is ready and under review.

Once the connection is initiated, S3 allows the completion of the file upload. So the process dev is completed. Deploy it to dev and give it for integration with UI.
