[kubectl apply of large CRDs/ConfigMaps] 'metadata.annotations: Too long: may not be more than 262144 bytes' — client-side apply stores the whole object in last-applied-configuration; use --server-si…

Cause (Documented platform behavior): API server limits total annotation size (TotalAnnotationSizeLimitB = 256 * 1024 bytes). Fix status: documented_behavior Limitations: - Rendered message typically 'metadata.annotations: Too long: may not be more than 262144 bytes'; verified as the format string + constant. - That server-side apply avoids the annotation is general Kubernetes behavior; the cited apply.go shows SSA flags and last-applied migration, not an explicit statement. - exact string is generic; match together with product/context Other error fragments: - Too long Evidence (public sources, summarized; not reproduced by this contributor): - https://raw.githubusercontent.com/kubernetes/kubernetes/6c1c7702cf2052245ef10e699d45f071af306f59/staging/src/k8s.io/apimachinery/pkg/api/validation/objectmeta.go (official_docs, unknown, documented_behavior): TotalAnnotationSizeLimitB = 256 KiB; ValidateAnnotations returns field.TooLong when total annotation size exceeds it. - https://raw.githubusercontent.com/kubernetes/kubernetes/6c1c7702cf2052245ef10e699d45f071af306f59/staging/src/k8s.io/apimachinery/pkg/util/validation/field/errors.go (official_docs, unknown, documented_behavior): TooLong detail 'may not be more than %d %s' (bytes); ErrorTypeTooLong renders as 'Too long'. - https://raw.githubusercontent.com/kubernetes/kubernetes/6c1c7702cf2052245ef10e699d45f071af306f59/staging/src/k8s.io/kubectl/pkg/util/apply.go (official_docs, unknown, documented_behavior): Client-side apply sets the LastAppliedConfigAnnotation to the serialized object. - https://raw.githubusercontent.com/kubernetes/kubernetes/6c1c7702cf2052245ef10e699d45f071af306f59/staging/src/k8s.io/kubectl/pkg/cmd/apply/apply.go (official_docs, unknown, documented_behavior): Server-side apply flags and constraints (--force-conflicts only with --server-side; --dry-run=client and --force incompatible with --server-side).
