+// A trace is a series of spans (often RPC calls) which form a latency tree.
+// 
+// The root span is where trace_id = id and parent_id = Nil. The root span is
+// usually the longest interval in the trace, starting with a SERVER_RECV
+// annotation and ending with a SERVER_SEND.
+// 
+// Attributes:
+//  - TraceID
+//  - Name: Span name in lowercase, rpc method for example
+// 
+// Conventionally, when the span name isn't known, name = "unknown".
+//  - ID
+//  - ParentID
+//  - Annotations
+//  - BinaryAnnotations
+//  - Debug
+//  - Timestamp: Microseconds from epoch of the creation of this span.
+// 
+// This value should be set directly by instrumentation, using the most
+// precise value possible. For example, gettimeofday or syncing nanoTime
+// against a tick of currentTimeMillis.
+// 
+// For compatibility with instrumentation that precede this field, collectors
+// or span stores can derive this via Annotation.timestamp.
+// For example, SERVER_RECV.timestamp or CLIENT_SEND.timestamp.
+// 
+// This field is optional for compatibility with old data: first-party span
+// stores are expected to support this at time of introduction.
+//  - Duration: Measurement of duration in microseconds, used to support queries.
+// 
+// This value should be set directly, where possible. Doing so encourages
+// precise measurement decoupled from problems of clocks, such as skew or NTP
+// updates causing time to move backwards.
+// 
+// For compatibility with instrumentation that precede this field, collectors
+// or span stores can derive this by subtracting Annotation.timestamp.
+// For example, SERVER_SEND.timestamp - SERVER_RECV.timestamp.
+// 
+// If this field is persisted as unset, zipkin will continue to work, except
+// duration query support will be implementation-specific. Similarly, setting
+// this field non-atomically is implementation-specific.
+// 
+// This field is i64 vs i32 to support spans longer than 35 minutes.
+//  - TraceIDHigh: Optional unique 8-byte additional identifier for a trace. If non zero, this
+// means the trace uses 128 bit traceIds instead of 64 bit.
