Defaults to `gcr.io/cloud-dataflow/v1beta3` ([#40569](https://github.com/apache/beam/issues/40569)). * (Go) GCS and Dataflow clients now support non-default universes such as Trusted Partner Cloud (TPC), using the universe domain from `GOOGLE_CLOUD_UNIVERSE_DOMAIN` or the default credentials. Added a `--gcs_endpoint` pipeline option to override the GCS endpoint ([#40569](https://github.com/apache/beam/issues/40569)). +* (Java) BigQuery Storage Write API `TableRow` conversion now resolves each field's protobuf descriptor by its schema ordinal, verified by name, instead of `Descriptor.findFieldByName` on every field, which cut conversion CPU by ~30% in a JMH benchmark ([#40188](https://github.com/apache/beam/issues/40188)). ## Breaking Changes diff --git a/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/TableRowToStorageApiProto.java b/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/TableRowToStorageApiProto.java index 687796ed5b47..803fd963e8b4 100644 --- a/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/TableRowToStorageApiProto.java +++ b/sdks/java/io/google-cloud-platform/src/main/java/org/apache/beam/sdk/io/gcp/bigquery/TableRowToStorageApiProto.java @@ -686,21 +686,37 @@ public static TableFieldSchema tableFieldToProtoTableField( } public static class SchemaInformation { + private static final int NO_FIELD_INDEX = -1; + private final TableFieldSchema tableFieldSchema; private final List subFields; private final Map subFieldsByName; private final Iterable parentSchemas; + /** + * Position of this field in its parent schema.
