If total_elapsed_time exceeds the maximum value for an integer (24.8 days in milliseconds), it will cause materialization failure due to overflow.The maximum value in milliseconds is equivalent to 24.8 days.| |is_available|`bit`|Flag indicating whether this node is available.|| |sent_time|`datetime`|Last time a network package was sent by this|| |received_time|`datetime`|Last time a network package was sent by this node.|| |error_id|`nvarchar(36)`|Unique identifier of the last error that occurred on this node.|| |compute_pool_id|`int`|Unique identifier for the pool.| ## See Also [PolyBase troubleshooting with dynamic management views](https://msdn.microsoft.com/library/ce9078b7-a750-4f47-b23e-90b83b783d80) [Dynamic Management Views and Functions (Transact-SQL)](~/relational-databases/system-dynamic-management-views/system-dynamic-management-views.md) [Database Related Dynamic Management Views (Transact-SQL)](../../relational-databases/system-dynamic-management-views/database-related-dynamic-management-views-transact-sql.md)
