Overview

Package pdata (pipeline data) implements data structures that represent telemetry data in-memory. All data received is converted into this format and travels through the pipeline in this format and that 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 in the future we are free to make changes to it to make more optimal.

Most of 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 it 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 allows to create more than one instance of the struct more efficiently instead of calling New* repeatedly. Use it where appropriate.

Types

type AttributeMap 

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

AttributeMap stores a map of attribute keys to values.

func NewAttributeMap 

func NewAttributeMap() AttributeMap

NewAttributeMap creates a AttributeMap with 0 elements.

func (AttributeMap) CopyTo 

func (am AttributeMap) CopyTo(dest AttributeMap)

CopyTo copies all elements from the current map to the dest.

func (AttributeMap) Delete 

func (am AttributeMap) Delete(key string) bool

Delete deletes the entry associated with the key and returns true if the key was present in the map, otherwise returns false.

func (AttributeMap) ForEach 

func (am AttributeMap) ForEach(f func(k string, v AttributeValue))

ForEach iterates over the every elements in the map by calling the provided func.

Example: 

it := sm.ForEach(func(k string, v StringValue) {
  ...
})

func (AttributeMap) Get 

func (am AttributeMap) Get(key string) (AttributeValue, bool)

Get returns the AttributeValue associated with the key and true. Returned AttributeValue is not a copy, it is a reference to the value stored in this map. It is allowed to modify the returned value using AttributeValue.Set* functions. Such modification will be applied to the value stored in this map.

If the key does not exist returns an invalid instance of the KeyValue and false. Calling any functions on the returned invalid instance will cause a panic.

InitEmptyWithCapacity constructs an empty AttributeMap with predefined slice capacity.

func (AttributeMap) InitFromAttributeMap added in v0.5.0 

func (am AttributeMap) InitFromAttributeMap(attrMap AttributeMap) AttributeMap

InitFromMap overwrites the entire AttributeMap and reconstructs the AttributeMap with values from the given map[string]string.

type AttributeValue 

type AttributeValue struct {

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)
