### OpenTelemetry batch configuration[​](#opentelemetry-batch-configuration "Direct link to OpenTelemetry batch configuration")

The SDK batches logs and traces through an OpenTelemetry `BatchSpanProcessor` before sending them to Coralogix. Use `otelConfig` to tune that batching — for example, to flush less frequently and reduce the number of network requests your app makes.

All fields are optional. Omitting `otelConfig` keeps the SDK defaults, and any out-of-range value is clamped to the documented bounds.

```
CoralogixRum.init({

  // ...

  otelConfig: {

    maxExportBatchSize: 50, // Max spans per export; reaching it triggers an early flush. Defaults to 50, min 1, max 256

    scheduledDelayMillis: 2000, // Delay in ms between two consecutive exports. Defaults to 2000(2s), min 2000(2s), max 30000(30s)

    maxQueueSize: 2048, // Max buffered spans before new spans are dropped. Defaults to 2048, min 512, max 4096

  },

});
```
