<p>When you create a resource group, you provide a name, CPU limit, and memory limit. You can optionally provide a concurrent transaction limit and memory shared quota and spill ratio. Use the <codeph><xref href="../ref_guide/sql_commands/CREATE_RESOURCE_GROUP.xml#topic1" type="topic" format="dita"/></codeph> command to create a new resource group. </p>

These limits identify the percentage of Greenplum Database resources

<title>Description</title>
<p>Creates a new resource group for Greenplum Database resource management. A resource
group is assigned to one or more roles and identifies concurrent transaction, memory,
and CPU limits for the role when resource groups are enabled. Only a superuser can create a resource group.</p>
and CPU limits for the role when resource groups are enabled.</p>
<p>You must have <codeph>SUPERUSER</codeph> privileges to create a resource group. The maximum number of resource groups allowed in your Greenplum Database cluster is 100.</p>
<p>Greenplum Database pre-defines two default resource groups: <codeph>admin_group</codeph>
and <codeph>default_group</codeph>. These group names are reserved.</p>
<p>The <codeph>max_resource_groups</codeph> server configuration parameter governs the maximum number of resource groups you can create.</p>
<p>
To set appropriate limits for resource groups, the Greenplum Database administrator must
be familiar with the queries typically executed on the system, as well as the users/roles executing those queries.</p>
