“The core technical value of this exploit kit lies in its comprehensive collection of iOS exploits,” Google researchers wrote. “The exploits feature extensive documentation, including docstrings and comments authored in native English. The most advanced ones are using non-public exploitation techniques and mitigation bypasses.”

For memory-intensive aggregations or sorting scenarios, users can use the settings max_bytes_before_external_group_by and max_bytes_before_external_sort respectively. The former of these is discussed extensively here. In summary, this ensures any aggregations can "spill" out to disk if a memory threshold is exceeded. This will impact query performance but will help ensure queries do not run out of memory. The latter sorting setting helps address similar issues with memory-intensive sorts. This can be particularly important in distributed environments where a coordinating node receives sorted responses from child shards. In this case, the coordinating server can be asked to sort a dataset larger than its available memory. With max_bytes_before_external_sort, sorting can be allowed to spill over to disk. This setting is also helpful for cases where the user has an ORDER BY after a GROUP BY with a LIMIT, especially in cases where the query is distributed.
