Segment growth rate

The segment growth rate calculation is useful when the ILI comparison is unable to get good results.

Before performing any comparison or analysis between two ILI reports, the user must verify the following parameters are consistent across both inspections:

• Detection Threshold: Ensure the detection threshold is the same in both ILI reports.
• Reporting Threshold: Ensure the reporting threshold is the same in both ILI reports.
• Tool Tolerances: Ensure the specified tool tolerances are the same in both ILI reports.

Failure to verify these parameters may result in inaccurate comparison or false growth assessments.

Input

Arguments

• org_id: as string which should be a valid uuid for the organization
• project_id: the id of the data project where the pipeline data is found
• pipeline_id: a array of string values representing a valid uuid for a pipeline
• older_ili_id: a array of string values representing a valid uuid for an ili report sequence
• newer_ili_id: a array of string values representing a valid uuid for an ili report sequence
• initial_segment_length: a float value
• depth_histogram_width: a float value
• length_histogram_width: a float value
• maximum_segment_length: a float value
• minimum_segment_length: a float value
• growth_rate_type: a string whose values should be one of
  • mean
  • maximum
• confidence: a string whose value should be one of
  • high
  • low

Creating the function on the platform

To create this function on the platform using the cli set up the port forwarding as shown in README.

Then run the following command to create the function.

cargo run functions create \
  -f functions/acr_segment_growth_rate \
  -d "Run the segment growth rate calculation" \
  -i org_id=string \
  -i project_id=string \
  -i pipeline_id=array \
  -i older_ili_id=array \
  -i newer_ili_id=array \
  -i initial_segment_length=integer \
  -i growth_rate_type=string \
  -i depth_histogram_width=float \
  -i length_histogram_width=float \
  -i confidence=float \
  -i maximum_segment_length=float \
  -i minimum_segment_length=float

Testing the function locally

You can run and test the function locally by running

cargo run

Then you can check it work with curl as follows

curl localhost:8080 -d $(jq '. | tojson' functions/acr_segment_growth_rate/example_input.json)
