Struct RetryConfig 

pub struct RetryConfig {
    pub max_retries: u32,
    pub retry_delay_ms: u64,
    pub use_backoff: bool,
}

Configuration for retry behavior with support for exponential backoff.

The RetryConfig allows fine-tuning of retry behavior for tasks that may experience transient failures. It provides:

• Configurable maximum retry attempts
• Fixed or exponential backoff strategies
• Customizable base delay between retries

Example

use dataflow_rs::engine::RetryConfig;

// Create config with exponential backoff
let config = RetryConfig {
    max_retries: 5,
    retry_delay_ms: 100,
    use_backoff: true,
};

// First retry: 100ms * 2^0 = 100ms
// Second retry: 100ms * 2^1 = 200ms
// Third retry: 100ms * 2^2 = 400ms

Fields

max_retries: u32

Maximum number of retries (0 means no retries)

retry_delay_ms: u64

Base delay between retries in milliseconds

use_backoff: bool

Whether to use exponential backoff (doubles delay each retry)
