How to enable OTEL disk buffering while using a custom BatchSpanProcessor configuration?

[agrognetti]

I noticed that when I enable the OTEL disk cache (In OTEL Android) like this:

OtelRumConfig()
    .setDiskBufferingConfig(
        DiskBufferingConfig.create(
            enabled = true
        )
    )

I can no longer use my own BatchSpanProcessor with a custom exporter, for example:

BatchSpanProcessor.builder(spanExporter)
    .setMaxQueueSize(BATCH_MAX_QUEUE_SIZE)
    .setScheduleDelay(BATCH_SCHEDULE_DELAY_MS, TimeUnit.MILLISECONDS)
    .setExporterTimeout(BATCH_EXPORTER_TIMEOUT_MS, TimeUnit.MILLISECONDS)
    .setMaxExportBatchSize(BATCH_MAX_EXPORT_SIZE)
    .build()

Instead, I have to rely on the default batch processor that OTEL creates internally.
It seems that to register my exporter, I must use:

rumBuilder.addLogRecordExporterCustomizer {
    // ...
}

However, this doesn’t allow me to configure parameters such as maxQueueSize, scheduleDelay, exporterTimeout, or maxExportBatchSize.

👉 Question:
Is there any way to use disk buffering and still define my own exporter and customized BatchSpanProcessor settings?
Or at least a way to override those parameters for the OTEL-managed processor?

hi @agrognetti! can you open this in the android repository?

Sure, I just opened an issue there
