- <p>A Greenplum Database workload is a resource group with special assignment
- capabilities. With Pivotal Greenplum Command Center, an administrator can
- create and manage workloads, and can define the criteria under which a transaction
- is assigned to a workload. This capability to assign transactions to workloads
- based on attributes other than the submitting role is unique to Greenplum Command
- Center.</p>
- <p>When you install and configure Greenplum Command Center, Greenplum Database
- defers the assignment of transactions to resource groups to the workload
- management component of the tool. You can also define idle session kill rules
- with Greenplum Command Center, specifying the maximum number of seconds that a
- session can remain idle before it kills itself. Refer to the
- <xref href="http://gpcc.docs.pivotal.io/latest" format="html"
- scope="external">Greenplum Command Center documentation</xref> for more
- information about creating and managing workloads, transaction assignment,
- and session kill rules.</p>
+ <p>Using Pivotal Greenplum Command Center, an administrator can create and manage resource
+ groups, change roles' resource groups, and create workload management rules. </p>
+ <p>Workload management rules are defined in Command Center and stored in Greenplum Database.
+ When a transaction is submitted, Greenplum Database calls the workload management database
+ extension to evaluate and apply the rules. </p>
+ <p>Workload management assignment rules assign transactions to different resource groups based
+ on user-defined criteria. If no assignment rule is matched, Greenplum Database assigns the
+ transaction to the role's default resource group. Workload management idle session kill
+ rules set the maximum number of seconds that sessions managed by a resource group can remain
+ idle before they are terminated.</p>
+ <p>Refer to the <xref href="http://gpcc.docs.pivotal.io/latest" format="html" scope="external"
+ >Greenplum Command Center documentation</xref> for more information about creating and
+ managing resource groups and workload management rules. </p>
