------------------------------
Summary: WriteToBigQuery Dynamic table destinations returns wrong
tableId
Key: BEAM-13487
URL: https://issues.apache.org/jira/browse/BEAM-13487
Project: Beam
Issue Type: Bug
Components: io-py-gcp
Affects Versions: 2.34.0
Reporter: Augusto
I am trying to write to bigquery to different table destinations and I would
like to create the tables dynamically if they don't exist already.
{code:java}
bigquery_rows | "Writing to Bigquery" >> WriteToBigQuery(lambda e:
compute_table_name(e),
schema=compute_table_schema,
additional_bq_parameters=additional_bq_parameters,
write_disposition=BigQueryDisposition.WRITE_APPEND,
create_disposition=BigQueryDisposition.CREATE_IF_NEEDED,
){code}
The function compute_table_name is quite simple actually, I am just trying to
get it to work.
{code:java}
def compute_table_name(element):
if element['table'] == 'table_id':
del element['table']
return "project_id:dataset.table_id" {code}
The schema is detected correctly and the table IS created and populated with
records. The problem is, the table ID I get is something along the lines of:
{code:java}
datasetId: 'dataset'
projectId: 'project_id'
tableId: 'beam_bq_job_LOAD_AUTOMATIC_JOB_NAME_LOAD_STEP... {code}
I have also tried returning a bigquery.TableReference object in my
compute_table_name function to no avail.
