// you can see the different points of view, which often help in debugging.
//
// Attributes:
//  - Key: Name used to lookup spans, such as "http.uri" or "finagle.version".
//  - Value: Serialized thrift bytes, in TBinaryProtocol format.

//
// There are two exceptions: when key is "ca" or "sa", this is the source or

// A trace is a series of spans (often RPC calls) which form a latency tree.
//
// Spans are usually created by instrumentation in RPC clients or servers, but
// can also represent in-process activity. Annotations in spans are similar to
// log statements, and are sometimes created directly by application developers
// to indicate events of interest, such as a cache miss.
//
// The root span is where parent_id = Nil; it usually has the longest duration
// in the trace.
//
// Span identifiers are packed into i64s, but should be treated opaquely.
// String encoding is fixed-width lower-hex, to avoid signed interpretation.
//
// Attributes:
//  - TraceID: Unique 8-byte identifier for a trace, set on all spans within it.
//  - Name: Span name in lowercase, rpc method for example. Conventionally, when the
// span name isn't known, name = "unknown".
//  - ID: Unique 8-byte identifier of this span within a trace. A span is uniquely
// identified in storage by (trace_id, id).
//  - ParentID: The parent's Span.id; absent if this the root span in a trace.
//  - Annotations: Associates events that explain latency with a timestamp. Unlike log
// statements, annotations are often codes: for example SERVER_RECV("sr").
// Annotations are sorted ascending by timestamp.
//  - BinaryAnnotations: Tags a span with context, usually to support query or aggregation. For
// example, a binary annotation key could be "http.uri".
//  - Debug: True is a request to store this span even if it overrides sampling policy.
//  - Timestamp: Epoch microseconds of the start of this span, absent if this an incomplete
// 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 compatibilty 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.
//
// Timestamp is nullable for input only. Spans without a timestamp cannot be
// presented in a timeline: Span stores should not output spans missing a
// timestamp.
//
// There are two known edge-cases where this could be absent: both cases
// exist when a collector receives a span in parts and a binary annotation
// precedes a timestamp. This is possible when..
//  - The span is in-flight (ex not yet received a timestamp)
//  - The span's start event was lost
//  - Duration: Measurement in microseconds of the critical path, if known.
//
// This value should be set directly, as opposed to implicitly via annotation
// timestamps. Doing so encourages precision 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.
