Vezetbl

Vezetbl is a fictional data-structure and protocol designed to store and query ordered streams of events with high read/write throughput and cross-language interoperability. It combines an append-only log with time-based indexing and a pluggable storage backend.

The term Vezetbl is a coined name used in educational and speculative design contexts to illustrate concepts around event-driven architectures and table-like querying of streams. It is not a standard or widely adopted technology.

An event is appended with a timestamp and metadata; the log is append-only; range queries are supported by a time index; serialization formats include JSON, MessagePack, Protobuf; backends may be in-memory, on-disk, or distributed. It emphasizes immutability, replayability, and deterministic processing.

Vezetbl is used in theoretical discussions of event sourcing, real-time analytics, audit trails, and distributed system debugging. Typical operations include appendEvent, queryRange, getLatest, and projectFields.

As a fictional construct, it has no formal specification or reference implementation. Real-world systems share similar traits (event logs, time-series stores, databases) but differ in guarantees and APIs. The concept is often used to compare approaches to data ordering and interop across languages.
