Research direction
Start by reading the linked lz4 issue and then locate TiFlash's compression implementation; no specific file or test is identified in this report. Clarify whether dictionary compression is supported and define measurable ratio and speed improvements before implementation. Done requires an agreed design and tests or benchmarks showing the result.
