pgflow 0.6.1 adds workerConfig to the handler execution context, enabling intelligent decision-making based on worker configuration.

Worker Configuration in Context

Handlers now have access to the complete worker configuration through context.workerConfig (#200). This enables smarter handlers that can adapt their behavior based on retry limits, concurrency settings, timeouts, and other worker parameters.

async function sendEmail(input, context) {
  const isLastAttempt = context.rawMessage.read_ct >= context.workerConfig.retry.limit;

  if (isLastAttempt) {
    // Use fallback email service on final attempt
    return await sendWithFallbackProvider(input.to, input.subject, input.body);
  }

  // Use primary email service for regular attempts
  return await sendWithPrimaryProvider(input.to, input.subject, input.body);
}

See the context documentation for complete details on available configuration properties and additional examples.

Bug Fix

This release also fixes retry strategy validation to only enforce the 50-limit cap for exponential retry strategy, allowing higher limits for fixed strategy when needed (#199).
