Laravel：超过了30秒的最大执行时间，如何优化查询？

Question

在地图上有太多请求（最多15000个）无法加载页面，这可能是由于它们搜索的是1对1产品，而不是一次全部获取。把整个关系放在哪里？     错误：

protected function runQueryCallback($query, $bindings, Closure $callback)
{
    // To execute the statement, we'll simply call the callback, which will actually
    // run the SQL against the PDO connection. Then we can calculate the time it
    // took to execute and log the query SQL, bindings and time in our memory.
    try {
        $result = $callback($this, $query, $bindings);
    }

    // If an exception occurs when attempting to run a query, we'll format the error
    // message to include the bindings with SQL, which will make this exception a
    // lot more helpful to the developer instead of just the database's errors.

        throw new QueryException(
            $query, $this->prepareBindings($bindings), $e
        );
