Service explained in plain language
DynamoDB is a managed key-value and document database. Its access model depends on how requests address and distribute data. Throttling means a request could not be served under the applicable capacity conditions; blindly repeating it faster can worsen the problem experienced by users.
Setup prerequisites and starting sequence
- Model the application's required reads and writes, including expected key distribution and peak demand. Choose the supported capacity configuration based on those requirements.
- Configure workload permissions, indexes and bounded retry behavior for the selected operations. Protect table data and establish recovery requirements.
- Build a representative load exercise and monitoring that distinguishes throttling from validation, authorization and application failures.
Start in non-production with the approved account/subscription, region and owner. Follow the linked service instructions for exact console/API options; provisioned resources may incur charges.
Example operational issue
A campaign concentrates many requests on a small part of an otherwise lightly used dataset. Aggregate traffic looks modest, yet a particular operation is repeatedly throttled. The investigation must consider the affected resource and access pattern rather than only total daily request count.
This is an illustrative operational example. Capture the exact error and time before making changes.
Troubleshooting: evidence before changes
| Observation | First check | Why it matters |
|---|---|---|
| Throttle responses affect one operation | Inspect the returned reason and the specific table or index involved | The limiting resource may differ from the top-level table operators first inspect. |
| Traffic clusters around a few keys | Compare the application access pattern with the data model | Uneven demand can require a design review rather than only a general capacity increase. |
| Retries multiply latency | Review retry count, backoff and end-to-end deadline | Aggressive retry loops can hide saturation and exceed the user response budget. |
Begin with status and scoped diagnostics. Sanitize shared evidence and escalate any check beyond your approved access.
Corrective action and change boundary
Select the supported capacity or data-access correction based on the measured cause. Test changes with realistic traffic and understand cost implications. Avoid redesigning partition keys or replaying a large write backlog directly in production without a migration and duplicate-processing plan.
Verification: what proves recovery
Repeat the representative operation and observe throttles, retry behavior, latency and business correctness. Include a controlled overload response in non-production. Confirm that the application exposes an actionable failure when its deadline is exceeded instead of retrying indefinitely.
Monitoring, SLI, SLO and SLA
Track successful business operations within their deadline, plus throttling and retry indicators. An internal SLO should include the latency consequence of retries, not count a late eventual success as if the user's original response objective was met.
SLI means the measured result; SLO means an agreed internal target. SLA means a contractual commitment with its own scope and remedy. The training targets here are examples, not vendor commitments; verify current service terms before promising an SLA.
A sample target could require 99% of valid test transactions to finish within the application deadline, with retry contribution explicitly recorded.
SOP and escalation handover
The data-model owner reviews key distribution; platform operations reviews capacity. Record request type, resource, throttle evidence and the tested correction. Escalate a change that affects stored-key design or substantial capacity cost before attempting an emergency broad rewrite.
SOP means standard operating procedure. Retain owner, evidence, approved change, reversal conditions and acceptance. Escalate with sanitized errors and resource identifiers.
Beginner glossary
Partition key: a primary addressing component. Throttling: capacity-related request refusal. Backoff: increasing the wait before another controlled attempt.
