  • total_entries (-) – the total number of entries attempted, successful or not

  • message (-) – the message for the exception group. If None, a default message

classmethod from_truncated_lists(first_list: list[Exception], last_list: list[Exception], total_excs: int, entry_count: int)

• Parameters

  • first_list (-) – the set of oldest exceptions to add to the ExceptionGroup

  • last_list (-) – the set of newest exceptions to add to the ExceptionGroup

Bases: google.cloud.bigtable.data.exceptions._BigtableExceptionGroup

Represents one or more exceptions that occur during a sharded read rows operation
