This PR introduces a cache (URL_PREFIX_CACHE) to store URL prefixes for all DatabaseDriver enums. By precomputing prefixes during initialization, the fromJdbcUrl method avoids redundant calls to getUrlPrefixes, significantly improving performance for repeated lookups.
Caching was chosen to reduce computational overhead while keeping the code maintainable. Future updates to getUrlPrefixes automatically reflect in the cache, requiring no additional changes.
