<p>Use the <codeph>MAX_SPILLED_RESULT_SPOOLING_MEM</codeph> query option to
set the maximum amount of memory that can be spilled when spooling query
results. </p>
<p>If the amount of memory exceeds this value when spooling query results,
the coordinator fragment will block until the client has consumed enough
rows to free up more memory.</p>
<p>The <codeph>MAX_SPILLED_RESULT_SPOOLING_MEM</codeph> query option is
applicable only when query result spooling is enabled with the
<codeph>SPOOL_QUERY_RESULTS</codeph> query option set to
<codeph>TRUE</codeph>. </p>
<p>The value must be greater than or equal to the value of
<p>Setting the option to <codeph>0</codeph> or <codeph>-1</codeph> means the
memory is unbounded. </p>
