Load data into Comet

This guide shows how to load exported data into Comet.

Before you start​

  • Export your data from Neptune using the Neptune Exporter tool. Start from the migration overview.
  • Get your Comet credentials:
    • Comet workspace. You can set it with the environment variable COMET_WORKSPACE or in the command line with --comet-workspace.
    • Comet API key. You can set it with the environment variable COMET_API_KEY or in the command line with --comet-api-key.

Validate your export​

Before loading the data into Comet, inspect what was exported:

uv run neptune-exporter summary --data-path ./exports/data

This command returns the number of exported projects or runs, attribute types, and the basic step statistics.

Load the data into Comet​

The following command loads the data into Comet, using the default data and file paths:

uv run neptune-exporter load \
  --loader comet \
  --comet-workspace my-workspace \
  --comet-api-key "$COMET_API_KEY" \
  --data-path ./exports/data \
  --files-path ./exports/files
