Detailed Description

Classes and functions for performing hedged requests.

Use MakeHedgedRedisRequest method to perform hedged redis request.

Example(Sync): auto result = ::redis::MakeHedgedRedisRequest<storages::redis::RequestHGet>( redis_client_shared_ptr, &storages::redis::Client::Hget, redis_cc, hedging_settings, key, field); Example(Async): auto future = ::redis::MakeHedgedRedisRequestAsync<storages::redis::RequestHGet>( redis_client_shared_ptr, &storages::redis::Client::Hget, redis_cc, hedging_settings, key, field); auto result = future.Get();
