 go-vshard-router is a library for sending requests to a sharded tarantool cluster directly,
 without using tarantool-router. This library based on [tarantool vhsard library router](https://github.com/tarantool/vshard/blob/master/vshard/router/init.lua) and [go-tarantool connector](https://github.com/tarantool/go-tarantool). go-vshard-router takes a new approach to creating your cluster

 go-vshard-router — библиотека для отправки запросов напрямую в стораджа в шардированный кластер tarantool,
 без использования tarantool-router.  Эта библиотека написана на основе [модуля библиотеки tarantool vhsard router](https://github.com/tarantool/vshard/blob/master/vshard/router/init.lua) и [коннектора go-tarantool](https://github.com/tarantool/go-tarantool). go-vshard-router применяет новый подход к созданию кластера
