EclipseLink is dedicated to being the best performing, and most scalable JPA implementation.
Contents
Features
EclipseLink's performance features include:
- Object cache
- Cache invalidation (time to live, and time of day)
- Configurable cache types per Entity, (Weak, Soft, SoftCache, HardCache, Full)
- Configurable cache size per Entity
- Clustered cache coordination
- Database change event invalidation (Oracle DCN)
- Cache indexes
- Querying
- Read-only queries
- Join fetching (query, nested, mapping)
- Batch fetching (IN, JOIN, EXISTS)
- Fetch groups (query, default, dynamic)
- Fetch size
- Pagination (firstResult, maxResult, ROWNUM filtering)
- Cursors (stream and scrollable)
- Cache usage (in-memory, primary key)
- Query cache (invalidation, size configuration)
- Mapping
- Lazy loading
- Read-only objects
- Weaving enhancements
- Transactions
- Attribute level change tracking
- Field level updates
