gcsDestination property
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.
