常见的想当然

A model expects span limits to apply a uniform eviction strategy across all collections, truncate string attributes by byte count, and enforce AttributeValueLengthLimit across span, event, and link attributes identically.

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• sdktrace.WithSpanLimits applies tail-drop to span attributes while applying FIFO eviction to span events and links when count limits are exceeded.
• Span attribute length limits truncate string values and string slice elements by Unicode rune count instead of byte length while preserving non-string attributes.
• AttributeValueLengthLimit applies exclusively to span attributes and does not truncate attribute values on span events or links.
• Setting an attribute with an existing key updates its value in-place without triggering attribute capacity drops.
• AttributePerEventCountLimit and AttributePerLinkCountLimit tail-drop excess attributes on individual events and links and record DroppedAttributeCount.
• Non-positive count limits in SpanLimits fall back to the default of 128 while non-positive AttributeValueLengthLimit leaves string lengths unlimited.
