The cache_max_size connection parameter specifies the maximum amount of memory to allocate for the file cache. By default,
the size is in bytes. Use k or m to specify units of kilobytes or megabytes.
If you exceed the maximum cache size, your platform's upper cache size limit is used instead. Note that UltraLite does not
grow the cache size beyond the actual file size of the database.
Any leading or trailing spaces in connection parameter values are ignored. This connection parameter's value cannot include
leading single quotes, leading double quotes, or semicolons.
