| WARNING: can cause deadlocks and performance issues when not used correctly. |
| <p> |
| Ignite performs cache operations using a special "striped" thread pool |
| (see <a class="xref" href="Apache.Ignite.Core.IgniteConfiguration.html#Apache_Ignite_Core_IgniteConfiguration_StripedThreadPoolSize">StripedThreadPoolSize</a>). Using this synchronous mode means that |
| async continuations (any code coming after <code>await cache.DoAsync()</code>, or code in <code>ContinueWith()</code>) |
| will run on the striped pool: |
| <ul> |
| <li> |
| Cache operations can't execute while user code runs on the striped thread. |
| </li> |
| <li> |
| Attempting other cache operations on the striped thread can cause a deadlock. |
| </li> |
| </ul> |
| <p> |
| This mode can improve performance, because continuations do not have to be scheduled on another thread. |
| However, special care is required to release striped threads as soon as possible.</p> |
