Required. Cloud Storage URIs to input files. Each URI can be up to 2000 characters long. URIs can match the full object path (for example,gs://bucket/directory/object.json) or a pattern matching one or more files, such asgs://bucket/directory/*.json.
A request can contain at most 100 files (or 100,000 files ifdataSchemaiscontent). Each file can be up to 2 GB (or 100 MB ifdataSchemaiscontent).
dataSchema
string
The schema to use when parsing the data from the source.
Supported values for document imports:
document(default): One JSONDocumentper line. Each document must have a validDocument.id.
content: Unstructured data (e.g. PDF, HTML). Each file matched byinputUrisbecomes a document, with the ID set to the first 128 bits of SHA256(URI) encoded as a hex string.
custom: One custom data JSON per row in arbitrary format that conforms to the definedSchemaof the data store. This can only be used by the GENERIC Data Store vertical.
csv: A CSV file with header conforming to the definedSchemaof the data store. Each entry after the header is imported as a Document. This can only be used by the GENERIC Data Store vertical.
