#platform_field_key(field) ⇒ Object

Implement this method in a subclass to apply custom tags to datadog spans def prepare_span(key, data, span) end

Parameters:

  • key (String) —

    The event being traced

  • data (Hash) —

    The runtime data for this event (@see GraphQL::Tracing for keys for each event)

  • span (Datadog::Tracing::SpanOperation) —

    The datadog span for this event
