fusion-datasource-cloner

A real Python CLI that clones a Lucidworks Fusion datasource in the same Fusion instance and also copies the linked configuration objects it references.

What it clones:

• datasource configuration
• linked index pipeline
• linked query pipeline
• linked index profile
• scheduler entries that reference the datasource
• optionally the parser

What it does not clone by default:

• collections and indexed data
• connector binaries / plugin jars
• blob contents referenced by custom stages

Install

python3 -m venv .venv
source .venv/bin/activate
pip install -r requirements.txt

Run

Basic auth:

python3 -m fusion_ds_clone.cli \
  --fusion-url https://fusion.example.com \
  --app demo \
  --basic-auth admin:password \
  --source-datasource products-json \
  --target-datasource products-json-copy \
  --verbose

API key:

python3 -m fusion_ds_clone.cli \
  --fusion-url https://fusion.example.com \
  --app demo \
  --api-key 'Bearer eyJhbGciOi...' \
  --source-datasource products-json \
  --target-datasource products-json-copy

Dry run:

python3 -m fusion_ds_clone.cli \
  --fusion-url https://fusion.example.com \
  --app demo \
  --basic-auth admin:password \
  --source-datasource products-json \
  --target-datasource products-json-copy \
  --dry-run

Clone and also move the clone to a different collection reference:

python3 -m fusion_ds_clone.cli \
  --fusion-url https://fusion.example.com \
  --app demo \
  --basic-auth admin:password \
  --source-datasource products-json \
  --target-datasource products-json-copy \
  --collection products_copy

Clone parser too:

python3 -m fusion_ds_clone.cli \
  --fusion-url https://fusion.example.com \
  --app demo \
  --basic-auth admin:password \
  --source-datasource products-json \
  --target-datasource products-json-copy \
  --clone-parser

Replace already-existing target objects:

python3 -m fusion_ds_clone.cli \
  --fusion-url https://fusion.example.com \
  --app demo \
  --basic-auth admin:password \
  --source-datasource products-json \
  --target-datasource products-json-copy \
  --overwrite

Notes

The tool derives new linked object IDs from the target datasource ID. Example:

• source datasource: my-source
• source index pipeline: my-source
• target datasource: my-source-copy
• target index pipeline: my-source-copy

If a linked object ID does not start with the source datasource ID, the tool creates a stable derived ID by suffixing the target datasource ID, for example:

• source query pipeline: shared-catalog-qp
• target query pipeline: shared-catalog-qp-my-source-copy

The parser API is still supported by the tool, but it is disabled by default because the current Lucidworks docs label parts of parser CRUD as deprecated.
