> h3. Reason of the test failures
> [org.apache.beam.sdk.io.gcp.testing.TableContainer|https://github.com/apache/beam/blob/6fa94c9/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/testing/TableContainer.java#L43] and [org.apache.beam.sdk.io.gcp.bigquery.BigQueryServicesImpl|https://github.com/apache/beam/blob/c2f0d28/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/BigQueryServicesImpl.java#L758] rely on {{TableRow.toString().length()}} to calculate the size. Example:
> {code:java}
>           dataSize += row.toString().length();
>           if (dataSize >= maxRowBatchSize
>               || rows.size() >= maxRowsPerBatch
>               || i == rowsToPublish.size() - 1) {
> {code}
> However, with [google-http-client's PR#589|https://github.com/googleapis/google-http-java-client/pull/589/files#diff-914cd7ff18143b3d2398149e1cfb4f45R218], the GenericData.toString output has changed since v1.29.0.
> In old google-http-client 1.28.0, an example row's toString returned:
> {noformat}
> {f=[{v=foo}, {v=1234}]}
> {noformat}
> In new google-http-client 1.29.0 and higher, the same row's toString returns:
> {noformat}
> GenericData{classInfo=[f], {f=[GenericData{classInfo=[v], {v=foo}}, GenericData{classInfo=[v], {v=1234}}]}}
> {noformat}
> h1. Question:
> Is this right thing to rely on {{toString().length()}} in the BigQuery classes?
