About rednote
rednote (Xiaohongshu) is a lifestyle community platform where people discover and share interests, experiences, and recommendations.
Reading fewer columns for real-time indexes
Search, recommendation, and advertising services consume different fields from the same wide tables. rednote moved its core indexing pipeline toward Fluss so each consumer can request only the columns it needs. The team reports 30% to 90% lower bandwidth usage across online workloads and approximately three times the peak throughput.
Separating historical builds from online traffic
Index builders read historical Fluss log files directly from object storage. This keeps large scans from competing with real-time consumers for broker bandwidth and cache. rednote reports that batch and incremental index construction became 50% to 80% faster.
Connecting the pipeline to Paimon
Fluss also tiers the data into Apache Paimon for exploration, migration validation, and historical analytics. Load tests, extended dual runs, and a phased rollout helped the team validate correctness and stability before moving core production traffic.
