Batch Processing: A batch of elements may contain elements associated\n * with one or more traces/spans. Since there can only be one parent\n * SpanContext, Link is used to keep reference to SpanContext of all\n * elements in the batch.\n * 2. Public Endpoint: A SpanContext in incoming client request on a public\n * endpoint is untrusted from service provider perspective. In such case it\n * is advisable to start a new trace with appropriate sampling decision.\n * However, it is desirable to associate incoming SpanContext to new trace\n * initiated on service provider side so two traces (from Client and from\n * Service Provider) can be correlated.\n */\nexport interface Link {\n /** The {@link SpanContext} of a linked span. */\n context: SpanContext;\n /** A set of {@link SpanAttributes} on the link. */\n attributes?: SpanAttributes;\n}\n"]} |
