The Summary of cache lock instances section of the Moodle Caching documentation is quite vague. All it says is:
"As mentioned above cache locking is an advanced concept in MUC.
The table here shows information on the configured locking mechanisms available to MUC. By default just a single locking mechanism is available, file locking. At present there are no caches that make use of this and as such I won't discuss it further here."
Is that still true in Moodle 3.7?
- Are there still "no caches that make use of this"?
- Under what circumstances would a Site Admin need to add a new lock instance? When and why would you need more than one?
