hitide-backfill-tool 0.12.1

Backfill footprints and images for HiTIDE collections

hitide-backfill-tool

Tool to backfill thumbnail images and footprints for POCLOUD datasets

Some granules have been ingested without creating footprints/thumbnail images. The purpose of this tool is to trigger part of Cumulus workflow to generate footprints and images for granules that need it.

What it does in a nutshell

• You specify search parameters at command line (collection, start_date, end_date, footprint, image, etc)
• Backfill-Tool searches CMR for matching granules
• Backfill-Tool figures out if the granule needs a footprint or image
• If footprint or image generation is needed, Backfill-Tool creates a Cumulus message and sends it to an AWS SNS topic.
• From there, another service will run trigger Forge/TIG and update CMR with new images/footprints as needed

Prerequisites

• Python > 3.10
• poetry

failed_workflow.py

• Script used to scan failed workflows and get unique errors
• Takes in three arguments
  • workflow_arn: arn of aws workflow
  • profile_name: aws profile name credential to use
  • limit: how many of latest execution to scan if not specified will go through all failed executions
• ex: python failed_workflow.py --workflow_arn arn:aws:states:us-west-2:123456:stateMachine:podaac-services-ops-hitide-backfill-forge --profile_name service_ops --limit 1000

replay.py

• Script used to get messages off dead letter queue and back into regular queue
• Takes 1 argument
  • config: configuration that has the aws_profile, dlq_url, and sqs_url
• ex: replay --config config.cfg

regression.py

• Script to run backfill tool command on all collection that has a forge-tig configuartion file
• Script can be modify to exclude or test specific collections

memory_profiler.py

• Script to run profile the memory use of lambdas, currently only tig is being profiled
• Lambdas need to be modified to include lambda request id in cloudwatch logs
• Modify script with cloudwatch lambda to profile
• Modify script to include start time and end time range where cloudwatch events were logged

ECS facility

• ECS template to start docker : ecs_cluster_instance_autoscaling_cf_template.yml.tmpl
• ECS script to execute task : task-reaper.sh
• All ECS related resources are specified in ecs_cluster.tf
• ECS is a cluster of EC2 instances. While creating the EC2 instances, a key is given to create each EC2 and the key name is specified as key_name variable within variables.tf. At this moment, the following keys are specified for each environment
  • backfill-tool-sit-cluster-keypair (SIT)
  • backfill-tool-uat-cluster-keypair (UAT)
  • backfill-tool-ops-cluster-keypair (OPS)
