| # Use shared client | ||
|
|
||
| ## General principle | ||
|
|
||
| ### Transport client | ||
|
|
||
| By default, Pandora components automatically assign it a transport client, such as for http, grpc, or tcp, when creating | ||
| a new Instance. When the Instance starts, it opens a connection, such as a tcp connection. | ||
| Normally, clients can use multiple connections at the same time, but in the case of Pandora, | ||
| each Instance opens only one connection as the Instance makes requests one after the other. | ||
|
|
||
| It's interesting to note that creating a connection doesn't mean that requests will go through that connection. Why? | ||
| In the test configuration, you can specify a large number of instances and a small number of RPSs. | ||
| The Pandora provider generates requests with the frequency specified in the RPS settings | ||
| and sends them to a random instance so that the instance will execute the request. | ||
|
|
||
| ## `shared-client`. | ||
| In the [http](../http-generator.md) and [grpc](../grpc-generator.md) generator settings, | ||
| you can specify the `shared-client.enabled=true` parameter. If you enable this setting, | ||
| all instances will use a shared transport client and each will not have to create its own. | ||
|
|
||
| ## `shared-client.client-number`. | ||
|
|
||
| The transport client uses to connect the connection. For example, HTTP and gRPC use a tcp connection. | ||
| A single client uses multiple connections and can create additional connections if needed. | ||
|
|
||
| But under heavy loads there may be a situation when the client does not have time to create connections. | ||
| You can increase the speed of connection creation by a common client by increasing the `shared-client.client-number` parameter. | ||
| By default `shared-client.client-number=1`. | ||

| # Использовать общий транспорт | ||
|
|
||
| ## Общий принцип | ||
|
|
||
| ### Транспортный клиент | ||
|
|
||
| По умолчанию, компоненты Pandora при создании нового Инстанса автоматически назначают ему транспортного клиента, | ||
| например, для http, grpc или tcp. Когда Инстанс запускается, он открывает соединение, например, tcp соединение. | ||
| Обычно, клиенты могут использовать несколько соединений одновременно, но в случае с Pandora, | ||
| каждый Инстанс открывает только одно соединение, так как Инстанс выполняет запросы один за другим. | ||
|
|
||
| Стоит заметить, что создание соединения не означает, что запросы будут идти через это соединение. Почему? | ||
| В настройках теста можно указать большое кол-во инстансов и маленькое кол-во RPS. | ||
| Провайдер Пандора генерирует запросы с частотой указаной в настройках RPS и передает на случайный инстанс, чтобы | ||
| инстанс выполнил этот запрос. | ||
|
|
||
| ## `shared-client` | ||
|
|
||
| В настройках генераторов [http](../http-generator.md) и [grpc](../grpc-generator.md) можно указать параметр `shared-client.enabled=true`. | ||
| Если включить данную настройку, то все инстансы будут использовать общий транспортный клиент и каждый не будет | ||
| создавать собственный. | ||
|
|
||
| ## `shared-client.client-number` | ||
|
|
||
| Транспортный клиент использует для подключения соединения. Например, HTTP и gRPC используют tcp соединение. | ||
| Один клиент использует нескоклько соединений. И может создавать дополнительные при непобходимости. | ||
|
|
||
| Но при больших нагрузках может возникнуть ситуация, когда клиент не успевает создать соединения. | ||
| Можно увеличить, скорость создания соединений общим клиентом, увеличив параметро `shared-client.client-number`. | ||
| По умолчанию `shared-client.client-number=1` | ||
|
