It allows clients to define the structure of the data required, and exactly the same structure of the data is returned from the server, therefore preventing excessively large amounts of data from being returned, but this has implications for how effective web caching of query results can be. The flexibility and richness of the query language also adds complexity that may not be worthwhile for simple APIs.[6][7][8]. It consists of a type system, query language and execution semantics, static validation, and type introspection. GraphQL supports reading, writing (mutating) and subscribing to changes to data (realtime updates).[9] Major GraphQL clients include Apollo Client[10] and Relay.[11] GraphQL servers are available for multiple languages, including Haskell, JavaScript[12], Python,[13] Ruby, Java, C#, Scala, Go, Elixir,[14] Erlang, PHP, R, and Clojure. On 9 February 2018, the GraphQL Schema Definition Language (SDL) was made part of the specification.[15] See also
