# Huge Traces configuration options
## `span_compression_enabled`

<applies-to>
  - Application Performance Monitoring Agent for Java: Generally available since 1.30
</applies-to>

Setting this option to true will enable span compression feature. Span compression reduces the collection, processing, and storage overhead, and removes clutter from the UI. The tradeoff is that some information such as DB statements of all the compressed spans will not be collected.

| Default | Type    | Dynamic |
|---------|---------|---------|
| `true`  | Boolean | true    |


| Java System Properties                 | Property file              | Environment                            |

## `span_compression_exact_match_max_duration`

<applies-to>
  - Application Performance Monitoring Agent for Java: Generally available since 1.30
</applies-to>

Consecutive spans that are exact match and that are under this threshold will be compressed into a single composite span. This option does not apply to composite spans. This reduces the collection, processing, and storage overhead, and removes clutter from the UI. The tradeoff is that the DB statements of all the compressed spans will not be collected.

Supports the duration suffixes `ms`, `s` and `m`. Example: `50ms`.

| Default | Type         | Dynamic |
|---------|--------------|---------|
| `50ms`  | TimeDuration | true    |

## `span_compression_same_kind_max_duration`

<applies-to>
  - Application Performance Monitoring Agent for Java: Generally available since 1.30
</applies-to>

Consecutive spans to the same destination that are under this threshold will be compressed into a single composite span. This option does not apply to composite spans. This reduces the collection, processing, and storage overhead, and removes clutter from the UI. The tradeoff is that the DB statements of all the compressed spans will not be collected.

Supports the duration suffixes `ms`, `s` and `m`. Example: `0ms`.

| Default | Type         | Dynamic |
|---------|--------------|---------|
| `0ms`   | TimeDuration | true    |


| Java System Properties                                | Property file                             | Environment                                           |

## `exit_span_min_duration`

<applies-to>
  - Application Performance Monitoring Agent for Java: Generally available since 1.30
</applies-to>

Exit spans are spans that represent a call to an external service, like a database. If such calls are very short, they are usually not relevant and can be ignored.
<note>
  If a span propagates distributed tracing ids, it will not be ignored, even if it is shorter than the configured threshold. This is to ensure that no broken traces are recorded.

Supports the duration suffixes `us`, `ms`, `s` and `m`. Example: `0ms`.
