Struct ProcessorConfig

pub struct ProcessorConfig {
    pub max_queue_size: usize,
}

Configuration for the Lambda span processor.

This struct allows customizing the behavior of the span processor to match your workload’s requirements. The configuration affects memory usage, span handling capacity, and potential span loss under high load.

Configuration Options

• max_queue_size: Maximum number of spans that can be stored in memory
  • Determines memory usage (each span ≈ 100-500 bytes)
  • When full, new spans are dropped with warning logs
  • Should be sized based on expected span volume

Environment Variables

The queue size can be configured using the LAMBDA_SPAN_PROCESSOR_QUEUE_SIZE environment variable. If not set, defaults to 2048 spans.

Example

use lambda_otel_lite::ProcessorConfig;

// Default configuration (2048 spans)
let config = ProcessorConfig::default();

// Custom configuration for high volume
let config = ProcessorConfig {
    max_queue_size: 4096,
};

Fields

max_queue_size: usize

Maximum number of spans that can be stored in memory
