Google Cloud Translation v3 API - Class BatchDocumentOutputConfig (3.9.0)

Reference documentation and code samples for the Google Cloud Translation v3 API class BatchDocumentOutputConfig.

Output configuration for BatchTranslateDocument request.

Google Cloud Storage destination for output content. For every single input document (for example, gs://a/b/c.[extension]), we generate at most 2 * n output files. (n is the # of target_language_codes in the BatchTranslateDocumentRequest).

While the input documents are being processed, we write/update an index file index.csv under gcs_destination.output_uri_prefix (for example, gs://translation_output/index.csv) The index file is generated/updated as new files are being translated. The format is:

input_document,target_language_code,translation_output,error_output, glossary_translation_output,glossary_error_output

input_document is one file we matched using gcs_source.input_uri. target_language_code is provided in the request. translation_output contains the translations. (details provided below) error_output contains the error message during processing of the file. Both translations_file and errors_file could be empty strings if we have no content to output. glossary_translation_output and glossary_error_output are the translated output/error when we apply glossaries. They could also be empty if we have no content to output.

Once a row is present in index.csv, the input/output matching never changes. Callers should also expect all the content in input_file are processed and ready to be consumed (that is, no partial output file is written).

Since index.csv will be keeping updated during the process, please make sure there is no custom retention policy applied on the output bucket that may avoid file updating. (https://cloud.google.com/storage/docs/bucket-lock#retention-policy)

The naming format of translation output files follows (for target language code [trg]): translation_output: gs://translation_output/a_b_c_[trg]_translation.[extension] glossary_translation_output: gs://translation_test/a_b_c_[trg]_glossary_translation.[extension]. The output document will maintain the same file format as the input document.

The naming format of error output files follows (for target language code [trg]): error_output: gs://translation_test/a_b_c_[trg]_errors.txt glossary_error_output: gs://translation_test/a_b_c_[trg]_glossary_translation.txt. The error output is a txt file containing error details.
