| <div class="paragraph"> |
| <p>A thin client is a lightweight Ignite client that connects to the cluster via a standard socket connection. |
| It does not become a part of the cluster topology, never holds any data, and is not used as a destination for compute grid calculations. |
| What it does is simply establish a socket connection to a standard Ignite node and perform all operations through that node.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Thin clients are based on the <a href="/docs/latest/binary-client-protocol/binary-client-protocol">binary client protocol</a>, which makes it possible to support Ignite connectivity from any programming language.</p> |

| <h3 id="client-connection-failover">Client Connection Failover</h3> |
| <div class="paragraph"> |
| <p>All thin clients support a connection failover mechanism, whereby the client automatically switches to an available node in case of the current node or connection failure. |
| For this mechanism to work, you need to provide a list of node addresses you want to use for failover purposes in the client configuration. |
| Refer to the specific client documentation for more details.</p> |

| <h3 id="partition-awareness">Partition Awareness</h3> |
| <div class="paragraph"> |
| <p>As explained in the <a href="/docs/latest/data-modeling/data-partitioning">Data Partitioning</a> section, data in the cluster is distributed between the nodes in a balanced manner for scalability and performance reasons. |
| Each cluster node maintains a subset of the data and the partition distribution map, which is used to determine the node that keeps the primary/backup copy of requested entries.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Partition awareness allows the thin client to send query requests directly to the node that owns the queried data.</p> |
| </div> |
| <div class="paragraph"> |
| <p>Without partition awareness, an application that is connected to the cluster via a thin client executes all queries and operations via a single server node that acts as a proxy for the incoming requests. |
| These operations are then re-routed to the node that stores the data that is being requested. |
| This results in a bottleneck that could prevent the application from scaling linearly.</p> |
