# `Excessibility.TelemetryCapture.Analyzers.DataGrowth`
[🔗](https://github.com/lessthanseventy/excessibility/blob/v0.18.1/lib/telemetry_capture/analyzers/data_growth.ex#L1)

Analyzes data growth patterns across timeline events.

Detects:
- Unbounded list growth (3x+ growth)
- Rapid growth (10x+ in single transition)
- Large growing lists (suggest pagination)

Uses data from the CollectionSize enricher (list_sizes) to track
how list sizes change over time.

## Algorithm

1. Track each list's size across events
2. Detect significant growth:
   - Warning: 3x+ growth overall
   - Critical: 10x+ growth in single step OR list exceeds 100 items
3. Suggest pagination for large growing lists (>100 items)

## Output

Returns findings and statistics:

    %{
      findings: [
        %{
          severity: :warning,
          message: "List 'products' growing: 10 → 50 → 200 (20x)",
          events: [1, 2, 3],
          metadata: %{
            list_name: :products,
            sizes: [10, 50, 200],
            growth_multiplier: 20.0
          }
        }
      ],
      stats: %{
        growing_lists: [:products, :users]
      }
    }
