Protobuf Encoding Principles and Optimization Techniques

The article explains how Protocol Buffers (proto3) encode basic and composite types using varint, zigzag, fixed-size and IEEE‑754 formats, describes tag and length field structures, and presents optimization strategies such as selecting size‑efficient types, flattening nested messages, and delta‑encoding to significantly reduce serialized byte‑stream size.

The Story Behind the Creation of UTF-8 and Its Advantages

Rob Pike and Ken Thompson devised UTF‑8 in 1992 at Bell Labs, turning a three‑day prototype into the web’s dominant Unicode encoding by using a variable‑length, ASCII‑compatible, length‑prefixed and prefix‑free scheme that maximizes efficiency, robustness, and universal adoption across more than 96 % of sites.

Redis Hash Internal Encoding: Ziplist vs Hashtable – Performance Analysis and Optimization

The incident showed that Redis hashes encoded as ziplist incur O(N) HEXISTS latency, causing high CPU on hot keys, while hashtable‑encoded hashes remain O(1); adjusting hash‑max‑ziplist settings or redesigning hot‑key patterns can convert to faster, though more memory‑hungry, hashtable encoding.
