QueryPlanNode
class QueryPlanNode( val sequence: Trace.QueryPlanNode.SequenceNode? = null, val parallel: Trace.QueryPlanNode.ParallelNode? = null, val fetch: Trace.QueryPlanNode.FetchNode? = null, val flatten: Trace.QueryPlanNode.FlattenNode? = null, val defer: Trace.QueryPlanNode.DeferNode? = null, val condition: Trace.QueryPlanNode.ConditionNode? = null, unknownFields: ByteString = ByteString.EMPTY) : Message<Trace.QueryPlanNode, Nothing>
represents a node in the query plan, under which there is a trace tree for that service fetch. In particular, each fetch node represents a call to an implementing service, and calls to implementing services may not be unique. See https://github.com/apollographql/federation/blob/main/query-planner-js/src/QueryPlan.ts for more information and details.

A DeferNode corresponds to one or more @defer at the same level of "nestedness" in the planned query.

This represents a node to send an operation to an implementing service

class FlattenNode( response_path: List<Trace.QueryPlanNode.ResponsePathElement> = emptyList(), val node: Trace.QueryPlanNode? = null, unknownFields: ByteString = ByteString.EMPTY) : Message<Trace.QueryPlanNode.FlattenNode, Nothing>
This node represents a way to reach into the response path and attach related entities. XXX Flatten is really not the right name and this node may be renamed in the query planner.
