Idempotent Producer Limits The Kafka idempotent producer, introduced in 0.11, guarantees that a message with a given producer ID and sequence number is written at most once to a partition. To preserve ordering, the feature requires that max.in.flight.requests.per.connection be set to 5 or less. Retry Handling and Partial Writes When a producer retries after
When using ESLint to automatically apply fixes, a custom rule that transforms source code may be invoked multiple times during a retry loop. Each invocation writes the same transformed content back to the file, resulting in duplicate write operations that clutter the version‑control history and can cause unnecessary rebuilds. The desired outcome is for the f
Context The Fetch API throws an AbortError when a request is cancelled via AbortController . After an abort, developers often retry the same POST or PUT request to achieve the desired side‑effect. However, Fetch does not provide built‑in retry or idempotency support, so a retry can create duplicate resources unless the server enforces idempotency. Unresolved
Goal We are moving our FaunaDB write path from manual client-side retry loops to driver-level retries combined with conditional FQL writes, and we need to prevent duplicate documents when a commit succeeds but the response is lost. Context and constraints Our collections are written from multiple regions, so we cannot rely on client-side timestamps for dedup
Goal: ensure that a Cloud Run service processing at-least-once messages does not perform duplicate writes when the invoking service retries delivery. Constraint: Cloud Run itself does not retry; the caller (e.g., Pub/Sub push or Cloud Tasks) may redeliver the same request with a potentially different value for the platform‑provided X‑Cloud‑Run‑Request‑ID hea
k3s forwards API requests to the underlying datastore without a de-duplication layer for POST operations. In HA mode with etcd, client libraries retry on transient errors and kubectl --retry repeats the HTTP request. The current configuration lacks an explicit idempotency guarantee for create operations. The goal is a consistent behavior for retries that avo
I am designing a retry-safe write path between a producer client and a receiving service that exchange XML documents. The plan is for the producer to embed a unique message ID and for the receiver to deduplicate on a digest of the canonicalized body, so a retried request returns the original result instead of applying the write twice. The open interoperabili
When using htmx's hx-retry attribute on a form that issues a POST request to create a resource, the goal is to prevent duplicate writes if the initial request succeeds but htmx retries due to a transient network error. htmx currently re‑issues the exact same request without any built‑in mechanism to detect that the server already processed the operation, so
A CI pipeline needs to retry a SonarQube analysis step when a run fails transiently, and the goal is that a resubmitted report produces exactly one current analysis per build — no duplicated issue counts and no polluted measure history. Two documented approaches exist. Re-running the scanner with the identical sonar.projectKey and sonar.branch.name replaces
