This wait type is when a thread is waiting for access to the data structure that contains performance metrics (RTDATA = RunTimeData) for natively-compiled stored procedures. The wait can occur when reporting metrics related to the execution statistics of a given stored procedure as well as when maintaining the data structure (e.g., cleaning up old data and keeping track of new data).

Maps to the XTP_RTDATA_LIST map_value in sys.dm_xe_map_values.
The map_key value in sys.dm_xe_map_values is 1016 in 2014 RTM. After 2014 RTM, you must check the DMV to get the latest value as some map_key values have changed in later builds.
There is a known bug in SQL Server 2014 (when using natively-compiled stored procedures) that can cause excessive waits on this wait type – see KB 3007050 for details.
