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