public static final class DataSourceDescriptor.Builder extends com.google.protobuf.GeneratedMessageV3.Builder<DataSourceDescriptor.Builder> implements DataSourceDescriptorOrBuilder
 Describes a data source containing one or more tensors. Enables multifield
 support where tensors within a source have different shapes.

 NOT a wire type: no message carries one, and no action returns one. A source
 crosses the wire only as its `sources` catalog row, and each SDK rebuilds
 this from that row as its own structural view. The shapes are identical --
 this is here to name the row's fields and their contract, not to be a second
 encoding of them. Do not put it back on an action.
