| The <code class="ph codeph">JOIN_ROWS_PRODUCED_LIMIT</code> query option limits the number of join |
| rows produced by a join node and is used to prevent runaway join queries. A query |
| is canceled when any one of the joins in the query produces more rows (totaled across |
| all instances of that join) than the specified limit set by the |
| <code class="ph codeph">JOIN_ROWS_PRODUCED_LIMIT</code> option. |
| </p> |
| |
| |
| <p class="p"> |
| This limit is checked periodically, so it is possible that the actual number of rows |
| produced may be slightly higher than the limit. |
| </p> |
| |
| |
| <p class="p"> |
| The default value of <code class="ph codeph">0</code> specifies that there is no limit on the number of |
| join rows produced. |
