"description":"A span represents a single timed event within a trace. Spans can be nested\nand form a trace tree. Often, a trace contains a root span that describes the\nend-to-end latency of an operation and, optionally, one or more subspans for\nits suboperations. Spans do not need to be contiguous. There may be gaps\nbetween spans in a trace.",
