docs - remove MADlib 1.11 note
<p>MADlib can be used with PivotalR, an R package that enables users to interact with data
resident in Greenplum Database using the R client. See <xref href="#topic_dxp_vq2_sv"
format="dita"/>.</p>
- <note>When using MADlib 1.11 and earlier, set the server configuration parameter
- <codeph>optimizer_control</codeph> to <codeph>on</codeph> (the default). If the parameter
- is set to <codeph>off</codeph>, these MADlib functions do not work: decision tree, random
- forest, LDA, k-Means, PMML export for decision tree, PMML export for random forest. <ph
- otherprops="pivotal">The installation checks for these functions also fail.</ph><p>The
- parameter <codeph>optimizer_control</codeph> controls whether the server configuration
- parameter <codeph>optimizer</codeph> can be changed. The parameter
- <codeph>optimizer</codeph> controls whether the GPORCA optimizer is enabled when running
- SQL queries. Some MADlib installation checks and functions change the value of
- <codeph>optimizer</codeph> to improve performance. If <codeph>optimizer_control</codeph>
- is set to <codeph>off</codeph>, the value of <codeph>optimizer</codeph> cannot be changed
- and the function fails. </p></note>
