Append Rows to Reference Data

POST 
/reference-datasets/:dataset_id/append

Append rows from a Parquet file to the current version. Maximum file size is 1GB.

The uploaded file's schema must match the current version exactly (same column names in the same order).

Not allowed when the dataset has a primary_key_column configured — append cannot enforce PK uniqueness against existing rows. Use POST /reference-datasets/{id}/records/upsert instead, which performs a PK-aware merge.

Parameters:

  • dataset_id: UUID of the reference dataset
  • file: Parquet file with rows to append (multipart/form-data)
