Tencent CLS: High‑Performance Time‑Series Search Engine for Cloud Log Service

Tencent’s Cloud Log Service augments Lucene with a dedicated time‑series index—using timestamp ordering, a secondary index, reverse binary search, and histogram optimization—to cut log query complexity, delivering up to 40‑50× faster responses, higher concurrency, and markedly better performance than traditional ELK‑style and competing cloud log solutions.
