  • datasource_name (str) – required name for datasource

  • bucket (str) – bucket for S3

  • assets (dict) – dict of asset configuration (required for ConfiguredAssetDataConnector)

  • execution_engine (ExecutionEngine) – optional reference to ExecutionEngine

  • default_regex (dict) – optional regex configuration for filtering data_references

  • sorters (list) – optional list of sorters for sorting data_references

  • prefix (str) – S3 prefix

  • max_keys (int) – S3 max_keys (default is 1000)

  • boto3_options (dict) – optional boto3 options

  • batch_spec_passthrough (dict) – dictionary with keys that will be added directly to batch_spec
