A new build of the MongoDB Extension has just been published, version 18.104.22.168. This version:
fixes an issue where cache entries with a “last access” timeout would not properly be removed from the cache in a timely manner.
fixes an issue where the hit count in the table was incremented twice on each “hit”
minor code cleanup (typos in function names)
Let me know if you have any questions. Also, I could use some help from someone with more Java experience than myself to update the extension to use the most recent major version of the official java driver. Please reach out if you are interested in contributing.
