Total paying users were 494,652 for the year ended December 31, 2024, compared to 557,692 for the year ended December 31, 2023.

The decrease was primarily attributable to a decrease of RMB123.7 million in the Company’s revenue sharing fees and a decrease of RMB26.5 million in the Company’s user acquisition costs due to the fact that the Company already had a stable market share. 

Gross profit increased by 27.4% to RMB245.4 million (US$33.6 million) for the year ended December 31, 2024 from RMB192.7 million for the year ended December 31, 2023. The gross margin increased to 18.0% for the year ended December 31, 2024 from 13.2% in the year ended December 31, 2023 due to higher average live streaming revenue per paying user (“ARPPU”) during the year ended December 31, 2024, showing the Company’s effectiveness in converting high-quality paying user to its profit growth.

Total operating expenses increased by 20.5% to RMB204.7 million (US$28.0 million) for the year ended December 31, 2024 from RMB169.9 million for the year ended December 31, 2023.

  • General and administrative expenses increased by1.4% to RMB76.6 million (US$10.5 million) for the year ended December 31, 2024 from RMB75.6 million for the year ended December 31, 2023.

  • Research and development expenses increased by 20.4% to RMB90.5 million (US$12.4 million) for the year ended December 31, 2024 from RMB75.1 million for the year ended December 31, 2023, due to an increase of RMB14.7 million in technical service fee and an increase of RMB1.1 million in employee salary and welfare.
  • Provision for credit losses increased by 71.2% to RMB30.6 million (US$4.2 million) for the year ended December 31, 2024 from RMB17.9 million for the year ended December 31, 2023, primary due to a one-time write-off of a RMB30.0 million investment buyback receivable.

Income from operations increased by 78.5% to RMB40.7 million (US$5.6 million) for the year ended December 31, 2024 from RMB22.8 million for the year ended December 31, 2023.

Change in fair value of contingent consideration was nil for the year ended December 31, 2024, as compared to a loss of RMB5.6 million for the year ended December 31, 2023.

Change in fair value of warrants liability was nil for the year ended December 31, 2024, as compared to a gain of RMB0.2 million for the year ended December 31, 2023. The fair value of the Company’s warrants derivative liability assumed from the SPAC acquisition is re-measured to its fair value at the end of each reporting period, with the change being recorded as other expense or gain. In February 2024, the Company’s warrants expired according to the terms of the warrant agreement.

Change in fair value of investment in marketable security was a gain of RMB6.1 million (US$0.8 million) for the year ended December 31, 2024, as compared to a loss of RMB9.0 million for the year ended December 31, 2023.

3. Write Fence Mechanism

a. Validates request versions at the storage layer, allowing writes only between adjacent states to eliminate data inconsistency risks.

4.  Fast OnlineDDL Acceleration

a.  Distributed Parallel Backfilling: Splits data into SST files for multi-node parallel ingestion via bulk load, bypassing timestamp comparisons to achieve 13x performance gains (10 minutes vs. 2.3 hours).

Practices & Optimizations

1. Performance Comparison

a. Traditional Mode (single-node): 16 threads took 2.3 hours.
b.  Fast Mode (multi-node): 48 threads completed in 10 minutes, showcasing significant efficiency improvements.

2. Partitioning Best Practices

a. Large Tables: Use HASH/KEY partitioning to distribute data evenly, enabling parallel DDL execution.
b. Cold/Hot Separation: Combine RANGE+HASH secondary partitioning for rapid cleanup and elastic scaling.
c. High Concurrency: Align partition keys with frequent query fields; set partition count as multiples of node numbers.

3.  Key Parameter Configuration

a. max_parallel_ddl_degree: Increase parallel threads (≤ total node CPUs).
b. tdsql_ddl_fillback_mode:  Enable IngestBehind mode to unlock multi-node parallel acceleration.

Business Value & Future Roadmap

  • Validated Use Cases: Achieved zero downtime in PB-scale financial systems, with 10x faster execution than third-party tools.
