# Group by Attributes

### Description

The Group by Attributes Processor groups telemetry with shared attribute values into the same resource.

### Use

1. "Promote" attributes so telemetry with those attributes gets grouped under a *resource* of that value.
2. [Compact](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/processor/groupbyattrsprocessor#compaction) telemetry data that shares a resource after batching.

### Configuration

<table><thead><tr><th width="156.08984375">Field</th><th>Description</th></tr></thead><tbody><tr><td>Telemetry Types</td><td>The types of telemetry to apply the processor to.</td></tr><tr><td>Attribute Keys</td><td>The attribute keys to group by and move to the resource. When no keys are specified, resources with the same attributes are compacted into the one resource.</td></tr></tbody></table>

### Example Configurations

#### 1. Promote an attribute

An example of promoting the `user` attribute on logs:

#### After:

#### 2. Compact telemetry with the same resource

By default, the processor will [compact](https://github.com/open-telemetry/opentelemetry-collector-contrib/tree/main/processor/groupbyattrsprocessor#compaction) telemetry that shares the same resource. Using this processor after the batch processor can reduce the amount of data sent to some destinations.
