Overview

Library entry point for performance metric reporting.

Events:

Key	Metadata
lex	{ query_string: String }
parse	{ query_string: String }
validate	{ query: GraphQL::Query, validate: Boolean }
analyze_multiplex	{ multiplex: GraphQL::Execution::Multiplex }
analyze_query	{ query: GraphQL::Query }
execute_multiplex	{ multiplex: GraphQL::Execution::Multiplex }
execute_query	{ query: GraphQL::Query }
execute_query_lazy	{ query: GraphQL::Query?, multiplex: GraphQL::Execution::Multiplex? }
execute_field	{ owner: Class, field: GraphQL::Schema::Field, query: GraphQL::Query, path: Array<String, Integer>, ast_node: GraphQL::Language::Nodes::Field}
execute_field_lazy	{ owner: Class, field: GraphQL::Schema::Field, query: GraphQL::Query, path: Array<String, Integer>, ast_node: GraphQL::Language::Nodes::Field}
authorized	{ context: GraphQL::Query::Context, type: Class, object: Object, path: Array<String, Integer> }
authorized_lazy	{ context: GraphQL::Query::Context, type: Class, object: Object, path: Array<String, Integer> }
resolve_type	{ context: GraphQL::Query::Context, type: Class, object: Object, path: Array<String, Integer> }
resolve_type_lazy	{ context: GraphQL::Query::Context, type: Class, object: Object, path: Array<String, Integer> }

Note that execute_field and execute_field_lazy receive different data in different settings:

• When using Execution::Interpreter, they receive {field:, path:, query:}
• Otherwise, they receive {context: ...}

Examples:

Sending custom events

query.trace("my_custom_event", { ... }) do
  # do stuff ...
end

Adding a tracer to a schema

class MySchema < GraphQL::Schema
  tracer MyTracer # <= responds to .trace(key, data, &block)
end

Adding a tracer to a single query

MySchema.execute(query_str, context: { backtrace: true })
