Overview

Package pdata (pipeline data) implements data structures that represent telemetry data in-memory. All data received is converted into this format, travels through the pipeline in this format, and is converted from this format by exporters when sending.

Current implementation primarily uses OTLP ProtoBuf structs as the underlying data structures for many of of the declared structs. We keep a pointer to OTLP protobuf in the "orig" member field. This allows efficient translation to/from OTLP wire protocol. Note that the underlying data structure is kept private so that we are free to make changes to it in the future.

Most of the internal data structures must be created via New* functions. Zero-initialized structures, in most cases, are not valid (read comments for each struct to know if that is the case). This is a slight deviation from idiomatic Go to avoid unnecessary pointer checks in dozens of functions which assume the invariant that "orig" member is non-nil. Several structures also provide New*Slice functions that allow creating more than one instance of the struct more efficiently instead of calling New* repeatedly. Use it where appropriate.

This package also provides common ways for decoding serialized bytes into protocol-specific in-memory data models (e.g. Zipkin Span). These data models can then be translated to pdata representations. Similarly, pdata types can be translated from a data model which can then be serialized into bytes.

* Encoding: Common interfaces for serializing/deserializing bytes from/to protocol-specific data models. * Translation: Common interfaces for translating protocol-specific data models from/to pdata types. * Marshaling: Common higher level APIs that do both encoding and translation of bytes and data model if going directly pdata types to bytes.

    ... // Do something with the element
}

Resize is an operation that resizes the slice: 1. If the newLen <= len then equivalent with slice[0:newLen:cap]. 2. If the newLen > len then (newLen - cap) empty elements will be appended to the slice.

Here is how a new AnyValueArray can be initialized:

es := NewAnyValueArray()
es.Resize(4)
for i := 0; i < es.Len(); i++ {
    e := es.At(i)
    // Here should set all the values for e.
}

InsertString adds the string Value to the map when the key does not exist. No action is applied to the map where the key already exists.

func (AttributeMap) Len

func (am AttributeMap) Len() int

Len returns the length of this map.

Because the AttributeMap is represented internally by a slice of pointers, and the data are comping from the wire, it is possible that when iterating using "Range" to get access to fewer elements because nil elements are skipped.

func (AttributeMap) Range added in v0.25.0

func (am AttributeMap) Range(f func(k string, v AttributeValue) bool)

Range calls f sequentially for each key and value present in the map. If f returns false, range stops the iteration.

type AttributeValue

type AttributeValue struct {
	// contains filtered or unexported fields
}

AttributeValue represents a value of an attribute. Typically used in AttributeMap. Must use one of NewAttributeValue+ functions below to create new instances.

Intended to be passed by value since internally it is just a pointer to actual value representation. For the same reason passing by value and calling setters will modify the original, e.g.:

function f1(val AttributeValue) { val.SetIntVal(234) }
function f2() {
    v := NewAttributeValueString("a string")
    f1(v)
    _ := v.Type() // this will return AttributeValueTypeInt
