Announcing: OIE Cache Manager Plugin — Now Available from Diridium Technologies
We’re excited to announce the release of OIE Cache Manager, an open-source plugin for Open Integration Engine (OIE) that delivers fast, in-memory key-value lookups against external databases.
What it does: Cache Manager uses Google Guava’s LoadingCache and HikariCP connection pooling to let your channels look up data from external databases at memory speed. The first call for a given key queries the database; every subsequent call returns instantly from cache.
Key Features:
- Lazy per-key loading with automatic eviction based on configurable max size and TTL
- HikariCP connection pooling to prevent connection storms under load
- Admin UI for creating, editing, duplicating, and managing cache definitions directly in OIE Administrator
- Cache Inspector for monitoring hit rates, memory usage, entry counts, and browsing cached data
- Full REST API with OpenAPI annotations
- Password encryption for database credentials at rest using OIE’s built-in encryptor
- Event logging integrated with OIE’s event system
Usage is simple — define a cache in the admin UI, then call it from any channel with a single line: $g('zip2').lookup(zip)
