Unlocking Hessian: How Java’s Binary Serialization Boosts Performance

This article explains the core principles of Hessian, a Java‑optimized binary serialization protocol, covering object graph traversal, encoding formats, data‑block tags, repeated‑object reuse, small‑integer inlining, and integer compression, and shows why it offers higher efficiency and compression than text‑based alternatives.

Understanding Redis Memory Model: Objects, Allocation, and Internal Encoding

This article explains Redis's memory model by describing how to query memory usage, the roles of used_memory, used_memory_rss, mem_fragmentation_ratio, and mem_allocator, and then dives into the internal structures such as redisObject, SDS, jemalloc, and the encoding strategies for strings, lists, hashes, sets, and sorted sets.
