Error: Dynamodb error 500

An HTTP 500 response from DynamoDB indicates an internal service error. It is distinct from validation failures and capacity throttling, which have their own error codes. Use the SDK’s retry behavior, but account for the possibility that a write succeeded before the error response.

1. Capture the exception code, request ID, operation, table, Region, and time. Check whether the SDK already retried the request.
2. Retry reads with bounded backoff. For writes, preserve the operation’s idempotency: a repeated increment can apply twice, while a conditional or tokenized transaction may provide the needed protection.
3. If a write’s result is uncertain, read back the intended state and reconcile before replaying it. A timeout after transmission has the same ambiguity.
4. For sustained failures, correlate SystemErrors with application impact and AWS Health, then provide request IDs to AWS Support.

Increasing provisioned throughput is not a general remedy for HTTP 500. If the response instead reports throttling, inspect ThrottlingReasons and the resource ARN. Avoid an unbounded retry loop that increases load during an incident.
