LoaderQuickSetup

class google_pandas_load.loader_quick_setup.LoaderQuickSetup(project_id=None, dataset_id=None, bucket_name=None, gs_dir_path=None, credentials=None, local_dir_path=None, generated_data_name_prefix=None, max_concurrent_google_jobs=40, use_wildcard=True, compress=True, separator='|', chunk_size=268435456, logger=<Logger LoaderQuickSetup (DEBUG)>)

Bases: google_pandas_load.loader.Loader

The purpose of this class is to quickly set up a loader.

An instance of LoaderQuickSetup is simply an instance of the base class built with the following arguments:

bq_client=bq_client
dataset_ref=dataset_ref
bucket=bucket
gs_dir_path=gs_dir_path
local_dir_path=local_dir_path
generated_data_name_prefix=generated_data_name_prefix
max_concurrent_google_jobs=max_concurrent_google_jobs
use_wildcard=use_wildcard
compress=compress
separator=separator
chunk_size=chunk_size
logger=logger

where

bq_client = google.cloud.bigquery.Client(
    project=project_id,
    credentials=credentials)
dataset_ref = google.cloud.bigquery.DatasetReference(
    project=project_id,
    dataset_id=dataset_id)
gs_client = google.cloud.storage.Client(
    project=project_id,
    credentials=credentials)
bucket = google.cloud.storage.Bucket(
    client=gs_client,
    name=bucket_name)

Parameters

• project_id (str, optional) – The project id.

• dataset_id (str, optional) – The dataset id.

• bucket_name (str, optional) – The bucket name.

• gs_dir_path (str, optional) – See base class.

• credentials (google.auth.credentials.Credentials) – Credentials used to build the bq_client and the bucket. If not passed, falls back to the default inferred from the environment.

• local_dir_path (str, optional) – See base class.

• generated_data_name_prefix (str, optional) – See base class.

• max_concurrent_google_jobs (int, optional) – See base class. Default value is 40 while the default value for the base class is 10. The first value is intended for a notebook environment whereas the second one for a production environment. In the latter case the amount of google computing resources is usually shared by several programs running in production.

• use_wildcard (bool, optional) – See base class.

• compress (bool, optional) – See base class.

• separator (str, optional) – See base class.

• chunk_size (int, optional) – See base class.

• logger (logging.Logger, optional) – See base class. Default value is a logger called LoaderQuickSetup. Contrary to the default base class logger, it is set to not propagate its log records to its logger ancestors and it is equipped with an handler displaying the log records to the console. This is, for instance, convenient when working with a notebook.
