  • datasource_name (str) – Name of datasource that this DataConnector is connected to

  • assets (dict) – configured assets as a dictionary. These can each have their own regex and sorters

  • execution_engine (ExecutionEngine) – ExecutionEngine object to actually read the data

  • default_regex (dict) – Optional dict the filter and organize the data_references.

  • glob_directive (str) – glob for selecting files in directory (defaults to **/*) or nested directories (e.g. */*/*.csv)

  • sorters (list) – Optional list if you want to sort the data_references

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