# Retry with Backoff Example
# Demonstrates automatic retry patterns for resilient API calls

# Simple retry - try up to 3 times on failure
session "Call flaky third-party API"
  retry: 3

# Retry with exponential backoff for rate-limited APIs
session "Query rate-limited service"
  retry: 5
  backoff: "exponential"

# Retry with linear backoff
session "Send webhook notification"
  retry: 3
  backoff: "linear"

# Combining retry with context passing
let config = session "Load API configuration"

session "Make authenticated API request"
  context: config
  retry: 3
  backoff: "exponential"

# Retry inside try/catch for fallback after all retries fail
try:
  session "Call primary payment processor"
    retry: 3
    backoff: "exponential"
catch:
  session "All retries failed - use backup payment processor"
    retry: 2

# Parallel retries for redundant services
parallel:
  primary = try:
    session "Query primary database"
      retry: 2
      backoff: "linear"
  catch:
    session "Primary DB unavailable"
  replica = try:
    session "Query replica database"
      retry: 2
      backoff: "linear"
  catch:
    session "Replica DB unavailable"

session "Merge results from available databases"
  context: { primary, replica }

# Retry in a loop for batch processing
let items = ["batch1", "batch2", "batch3"]
for item in items:
  try:
    session "Process this batch item"
      context: item
      retry: 2
      backoff: "exponential"
  catch:
    session "Log failed batch for manual review"
      context: item
