BenchMark Result of TsFile for multi languages[C/C++, Java, Python] #460
Description
The total writing time includes both data preparation time and writing time. Writing throughput is calculated based on the total write duration.
Reading throughput is calculated based on the time taken to traverse all data.
The benchmark writes 1,000 Tablets, where each Tablet contains 2 tag columns, 5 field columns, and 10 devices - collectively representing 50 time series. Every time series within a Tablet comprises 1,000 timestamped data points. The measurement captures two key metrics: (1) the preparation time required to construct each Tablet, and (2) the execution time for individual write operations. This setup generates 50 million data points (1,000 Tablets × 50 series × 1,000 points) for comprehensive performance evaluation of the tsfile.
