// Indicates the network context of a service recording an annotation with two

//
// When a BinaryAnnotation, and key is CLIENT_ADDR or SERVER_ADDR,
// the endpoint indicates the source or destination of an RPC. This exception
// allows zipkin to display network context of uninstrumented services, or
// clients such as web browsers.
//
// Attributes:
// - Ipv4: IPv4 host address packed into 4 bytes.
//
// Ex for the ip 1.2.3.4, it would be (1 << 24) | (2 << 16) | (3 << 8) | 4
// - Port: IPv4 port or 0, if unknown.
//
// Note: this is to be treated as an unsigned integer, so watch for negatives.
// - ServiceName: Classifier of a source or destination in lowercase, such as "zipkin-web".
//
// This is the primary parameter for trace lookup, so should be intuitive as
// possible, for example, matching names in service discovery.
//
// Conventionally, when the service name isn't known, service_name = "unknown".
// However, it is also permissible to set service_name = "" (empty string).
// The difference in the latter usage is that the span will not be queryable
// by service name unless more information is added to the span with non-empty
// service name, e.g. an additional annotation from the server.
//
// Particularly clients may not have a reliable service name at ingest. One
// approach is to set service_name to "" at ingest, and later assign a
// better label based on binary annotations, such as user agent.
// - Ipv6: IPv6 host address packed into 16 bytes. Ex Inet6Address.getBytes()

// Binary annotations are tags applied to a Span to give it context. For

//
// Binary annotations of type STRING are always queryable, though more a
// historical implementation detail than a structural concern.
//
// Binary annotations can repeat, and vary on the host. Similar to Annotation,
// the host indicates who logged the event. This allows you to tell the
// difference between the client and server side of the same key. For example,
// the key "http.path" might be different on the client and server side due to
// rewriting, like "/api/v1/myresource" vs "/myresource. Via the host field,
// you can see the different points of view, which often help in debugging.
//
// Attributes:
// - Key: Name used to lookup spans, such as "http.path" or "finagle.version".
// - Value: Serialized thrift bytes, in TBinaryProtocol format.
//
// For legacy reasons, byte order is big-endian. See THRIFT-3217.
// - AnnotationType: The thrift type of value, most often STRING.
//
// annotation_type shouldn't vary for the same key.
// - Host: The host that recorded value, allowing query by service name or address.

// context of uninstrumented services, such as browsers or databases.

// 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.path".
// - 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 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.
//
// 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. Durations of
// less than one microsecond must be rounded up to 1 microsecond.
//
// 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.
// - 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.
