Functions

func BQSchemaToStorageTableSchema

func BQSchemaToStorageTableSchema(in bigquery.Schema) (*storagepb.TableSchema, error)

BQSchemaToStorageTableSchema converts a bigquery Schema into the protobuf-based TableSchema used by the BigQuery Storage WriteClient.

func StorageSchemaToProto2Descriptor

func StorageSchemaToProto2Descriptor(inSchema *storagepb.TableSchema, scope string) (protoreflect.Descriptor, error)

StorageSchemaToProto2Descriptor builds a protoreflect.Descriptor for a given table schema using proto2 syntax.

func StorageSchemaToProto3Descriptor

func StorageSchemaToProto3Descriptor(inSchema *storagepb.TableSchema, scope string) (protoreflect.Descriptor, error)

StorageSchemaToProto3Descriptor builds a protoreflect.Descriptor for a given table schema using proto3 syntax.

NOTE: Currently the write API doesn't yet support proto3 behaviors (default value, wrapper types, etc), but this is provided for completeness.

func StorageTableSchemaToBQSchema

func StorageTableSchemaToBQSchema(in *storagepb.TableSchema) (bigquery.Schema, error)

StorageTableSchemaToBQSchema converts a TableSchema from the BigQuery Storage WriteClient into the equivalent BigQuery Schema.
