| Ignites's In-Memory Data Fabric for .NET is designed to deliver uncompromised |
| performance for a wide set of in-memory computing use cases on top of .NET platform - |
| from high performance computing, to the industry most advanced data grid, CEP, and data streaming - all through native, optimized .NET APIs. |
| </p> |
| |
| <p> |
| Ignite .NET is built on top of Ignite. This allows you to perform almost all the in-memory data grid operations including |
| <span style="white-space: nowrap"><a href="https://apacheignite-net.readme.io/docs/transactions" target="_blank">ACID Transactions</a></span>, |
| <a href="https://apacheignite-sql.readme.io/docs/net-sql-api" target="_blank">SQL Queries</a>, |
| <a href="https://apacheignite-sql.readme.io/docs/net-sql-api#section-sqlquery" target="_blank">Distributed SQL Joins</a>, |
| <a href="https://apacheignite-net.readme.io/docs/topic-based" target="_blank">Messaging</a> and <a href="https://apacheignite-net.readme.io/docs/local-and-remote-events" target="_blank">Events</a>, |
| <a href="https://apacheignite-net.readme.io/docs/streaming" target="_blank">Data Streaming</a>, and more, on replicated or partitioned caches distributed across the cluster. |
| </p> |
| <p> |
| Ignite also supports <span style="white-space: nowrap"><a href="https://apacheignite-net.readme.io/docs/platform-interoperability" target="_blank">Cross-Platform Interoperability</a></span> |
| allowing applications to seamlessly interoperate between <b>Java</b>, <b>.NET</b> and <b>C++</b> by writing/reading objects to/from cache in a common binary format. |
| Additionally, both Ignite .NET and Ignite C++ provide native APIs and their implementations that delegate most of the calls to Java using JNI. |
| Here, it is worth mentioning that the JNI overhead is minimal and does not cause any performance degradation, especially in distributed environments where network is the main obstacle. |
| Furthermore, Ignite provides a pure .NET implementation of the Binary Marshaller to contribute to the perfomance. |
