This advisory condition will return true if any table in the specified database has at least 10% skew between the smallest and largest distribution.
The AC checks this condition every 8 hours by default, and triggers any configured actions as soon as it evaluates True.
Because this condition queries system views, it times out after 1 minute by default.
When applying, edit this condition and replace the Database name with the name of the database you wish to monitor on APS.
Excessive skew may suggest you need to distribute this table on a different key.
