|
| <div class="markdown level0 summary"><p>A page memory configuration for an Apache Ignite node. The page memory is a manageable off-heap based |
| memory architecture that divides all continuously allocated memory regions into pages of fixed size. |
| An individual page can store one or many cache key-value entries that allows reusing the memory |
| in the most efficient way and avoid memory fragmentation issues. |
| <p> |
| By default, the page memory allocates a single continuous memory region. All the caches that |
| will be configured in an application will be mapped to this memory region by default, |
| thus, all the cache data will reside in that memory region. |
| <p> |
| If initial size of the default memory region doesn't satisfy requirements or it's |
| required to have multiple memory regions with different properties |
| then <a class="xref" href="Apache.Ignite.Core.Cache.Configuration.MemoryPolicyConfiguration.html">MemoryPolicyConfiguration</a> can be used for both scenarios. |
| For instance, using memory policies you can define memory regions of different maximum size, |
| eviction policies, swapping options, etc. Once you define a new memory region you can bind |
| particular Ignite caches to it. <p> |
| To learn more about memory policies refer to <a class="xref" href="Apache.Ignite.Core.Cache.Configuration.MemoryPolicyConfiguration.html">MemoryPolicyConfiguration</a> documentation. |
| <p> |
| Obsolete, use <a class="xref" href="Apache.Ignite.Core.Configuration.DataStorageConfiguration.html">DataStorageConfiguration</a>.</p> |
