History

4.0.0 (2021-04-13)

API Changes

  • google-cloud-bigquery==2.* is now required.

  • infer_datetime_format is removed from the arguments of the load methods. It is set to True for pandas.read_csv when data is loaded from ‘local’ to ‘dataframe’.

  • generated_data_name_prefix is removed from loader’s arguments. It is now impossible to add a custom prefix to generated data_names.

  • max_concurrent_google_jobs is removed from loader’s arguments. Concurrency of bq_client jobs is now solely handled by google.

  • use_wildcard is removed from loader’s arguments. A wildcard is now always used when data is loaded from ‘bq’ to ‘gs’.

  • compress is removed from loader’s arguments. Data is now always compressed when loaded from ‘bq’ to ‘gs’ or from ‘dataframe’ to ‘local’.

Notes

  • We use new conventions for naming some BigQuery objects. This causes only one API change (the second one in the API Changes section above). Let us describe the new conventions with an example. Suppose we have a BigQuery table whose address is project1.dataset1.table1. We say that:

    • project1 is a project_id.

    • project1.dataset1 is a dataset_id.

    • project1.dataset1.table1 is a table_id.

    • dataset1 is a dataset_name.

    • table1 is a table_name.

2.0.1 (2019-12-20)

Improvement

  • The data is deleted in transitional locations even if its transfer fails.

Bugfixes

  • The method google.cloud.bigquery.job.QueryJob.result() is used again to wait for a google job to be completed. The timeout bug described in the previous “bugfixes” seems to be due to a Docker configuration problem.

  • The end of a step “query_to_bq” produced the log: “Ended source to bq”. It has been corrected to “Ended query to bq”.

2.0.0 (2019-12-04)

API Changes

  • The parameters delete_in_bq, delete_in_gs and delete_in_local of of google_pandas_load.loader.Loader.load() do not exist anymore. There were used to choose if data had to be deleted once loaded to the next location. The new behavior is now the following:

    • The data is kept in the source.

    • The data is deleted in transitional locations after being transferred.

    This behavior is safer, simpler to understand and fits to the common use.

  • The destination parameter of google_pandas_load.loader.Loader.load() can no longer be set to ‘query’ since it appeared to be useless. It is now restricted to ‘bq’, ‘gs’, ‘local’ or ‘dataframe’.

  • The gs_dir_path_in_bucket parameter of google_pandas_load.loader.Loader has been renamed gs_dir_path.

  • google_pandas_load.loader.Loader has now the following getter functions: bq_client, dataset_ref, bucket, gs_dir_path and local_dir_path. They return the homonym arguments of the class.

  • google_pandas_load.loader_quick_setup.LoaderQuickSetup has three new getter functions: project_id, dataset_id and bucket_name. They return the homonym arguments of the class.

Bugfixes

  • The method google.cloud.bigquery.job.QueryJob.result() was used to wait for a google job to be completed. It appeared it could lead to a timeout if the google job was too long to run and is threfore no longer used. Instead, the google job is reloaded every second until it is completed.

  • Initial release on PyPI.
