Bruno Candido Volpato da Cunha commented on BEAM-12356:
-------------------------------------------------------
This error is reproducible on 2.37.0 as well.
However, it seems to be on the Reader side of the BigQueryIO, not the writer.
A huge leak of Gax-* threads can be seen, after running a Beam job using this
source:
{code:java}
PCollection<TableRow> tableRows =
pipeline.apply(
"Read from BigQuery",
BigQueryIO.readTableRows()
.from(
new TableReference()
.setProjectId(params.getTableProjectName())
.setDatasetId(params.getTableDatasetName())
.setTableId(params.getTableName()))
.withMethod(Method.DIRECT_READ)); {code}
Apparently, BigQueryServicesImpl doesn't `.close()` the Bigquery instance
`client`. Will try to get more details and post them here.
> BigQueryWriteClient in DatasetServiceImpl is not closed, which causes
> "ManagedChannel allocation site" exceptions
