Jia Cache

Overview

Jia Cache is an upcoming high-performance distributed caching solution built entirely on the MVP.Express stack. It leverages the zero-copy capabilities of Myra Transport and Myra Codec to deliver unprecedented caching performance.

Planned Features

Performance

• Sub-millisecond latency for cache operations
• Zero-copy value retrieval directly to application buffers
• Off-heap storage eliminating GC pressure
• io_uring networking for maximum throughput

Distribution

• Consistent hashing for data distribution
• Replication for fault tolerance
• Automatic failover with leader election
• Cross-datacenter replication support

Data Structures

• Key-Value: Basic get/set/delete operations
• Lists: Ordered collections with push/pop
• Sets: Unique value collections
• Sorted Sets: Score-ordered unique values
• Maps: Nested key-value structures

Operations

• Atomic operations: CAS, increment, append
• TTL support: Per-key expiration
• Eviction policies: LRU, LFU, random
• Pub/Sub: Real-time notifications
