Resource Context

The Resource Context is a Context implementation for pdata Resources, the Collector's internal representation for an OTLP Resource. This Context should be used when interacting only with OTLP resources.

Paths

In general, the Resource Context supports accessing pdata using the field names from the resource proto. All integers are returned and set via int64. All doubles are returned and set via float64.

The following paths are supported.

path	field accessed	type
cache	the value of the current transform context's temporary cache. cache can be used as a temporary placeholder for data during complex transformations	pcommon.Map
cache[""]	the value of an item in cache. Supports multiple indexes to access nested fields.	string, bool, int64, float64, pcommon.Map, pcommon.Slice, []byte or nil
attributes	attributes of the resource being processed	pcommon.Map
attributes[""]	the value of the attribute of the resource being processed. Supports multiple indexes to access nested fields.	string, bool, int64, float64, pcommon.Map, pcommon.Slice, []byte or nil
dropped_attributes_count	number of dropped attributes of the resource being processed	int64

Enums

The Resource Context does not define any Enums at this time.
