No description provided.

* Changes to a query definition invalidate the cached plan for that query. Changes that only substitute constant values do not invalidate the cached query plan.
* When the query plan cache reaches its configured capacity, older cached plans are evicted to make room for new entries.

The query plan cache is stored in memory and is cleared when GPE is restarted.

Upon restarting other services, won't it get cleared? Just GPE restart will have an impact?
