gqldb-importer is the bulk-import tool of the Ultipa Transporter suite. It reads from external sources and writes nodes and edges into a GQLDB graph in batched, multi-threaded fashion.
gqldb-importer is configuration-driven. The typical workflow is:
Bash# 1. Generate a sample configuration (writes ./import.sample.<type>.yml) ./gqldb-importer -sample csv # 2. Rename / edit it mv import.sample.csv.yml my-import.yml # 3. Run the import ./gqldb-importer -c my-import.yml
Use -sample all to generate sample configurations for every supported source at once.
See Import Configurations for the full configuration reference.
