Region Shortcuts

This topic describes the various region shortcuts you can use to configure Geode regions.

Region shortcuts are groupings of pre-configured attributes that define the characteristics of a region. You can use a region shortcut as a starting point when configuring regions and you can add additional configurations to customize your application. To reference a region shortcut in a Geode cache.xml file, use the refid attribute of the <region> element. For example:

<region name="myRegion" refid="PARTITION_REDUNDANT"/>

You can override the default values and add additional configurations within a <region-attributes> element of the cache.xml file. For example, the following configuration overrides the local-max-memory setting and adds the recovery-delay attribute:

<region name="myRegion" refid="PARTITION_REDUNDANT">
    <region-attributes>
        <partition-attributes 
          local-max-memory="512" 
           recovery-delay=-1/>
    </region-attributes>
</region>

You can also create your own, named region shortcuts for common custom configurations. See Region Shortcuts and Custom Named Region Attributes.

To configure a region using the gfsh command-line tool, specify the shortcut name with the --type argument. For example:

gfsh>create region --name=myRegion --type=PARTITION_REDUNDANT

Note: If you change the cache.xml file that defines a region, you must restart the member before the changes take effect.
