Hi all, here is the board report for this quarter. ## Description: Apache TsFile is a columnar storage file format designed specifically for time series data, with a focus on efficient storage, high throughput for read and write operations, and compatibility with various data processing frameworks. TsFile is intended to integrate seamlessly with existing time series databases, such as IoTDB, and data processing frameworks like Apache Spark and Apache Flink, facilitating the adoption of TsFile in IoT big data processing ecosystems.TsFile aims to become a widely adopted standard for time series data storage.
## Project Status: Current project status: Mostly Okay Issues for the board: no ## Membership Data: Apache TsFile was founded 2023-11-15 (a year ago) There are currently 18 committers and 18 PMC members in this project. The Committer-to-PMC ratio is 1:1. Community changes, past quarter: - No new PMC members. Last addition was Gaofei Cao on 2023-11-15. - No new committers were added. ## Project Activity: 1.1.0 was released on 2024-11-10. Introduce short-circuit evaluation and use Freemarker to generate type-specific filters to improve the query performance Utilize the KMP and BM algorithms to significantly optimize the performance of LIKE predicate execution. Introduce an optional encryption module to make TsFile more secure. Support dictionary encoding for newly introduced STRING data type. ## Community Health: The activity level of the mailing list has declined a bit, as the development of TsFile V4 almost finished. There aren't many design points that need discussion. [email protected] had a 47% decrease in traffic in the past quarter (64 emails compared to 119): We are designing the new read and write interfaces for TsFile, aiming to make the interfaces in different programming languages more consistent in use. Both for V3 (Point Tree model) and V4 (Device Table model). Jialin Qiao
