## 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. * Support new data types: STRING, BLOB, TIMESTAMP, DATE * Introduce an optional encryption module to make TsFile more secure. * Support dictionary encoding for newly introduced STRING data type. Some optimizaitons: * We 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. ## 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. dev@tsfile.apache.org 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).
## Description: The mission of Apache TsFile is the creation and maintenance of software related to a columnar storage file format designed for time series data ## Project Status: Current project status: Ongoing with high activity. Issues for the board: no ## Membership Data: Apache TsFile was founded 2023-11-15 (9 months 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: Support four new data types in TsFile, including Date, Timestamp, String and Blob. Add the implementation of C++ TsFile, with C, Python SDK. Introducing Lazy-decoding of page data in PageReader to improve the query performance and memory footprint. Fix RLBE Encoding for float and double, from lossy to lossless. Improve the performance of InFilter. TsFile v4 is almost ready for development. ## Community Health: The mail list is active. dev@tsfile.apache.org had a 170% increase in traffic in the past quarter (127 emails compared to 47)

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: * Refactor the project's directory structure to prepare for the subsequent implementation of TsFile in other languages like C/C++, Rust and so on. * In order to support for table models, the structure of TsFile V4 has been finalized and is currently under implementation. * Release a snapshot version `1.0.1-4ab90f6-SNAPSHOT` for IoTDB Project which has removed all the source code files about tsfile submudole in its master branch and depend on TsFile project through pom.xml. ## Community Health: The mail list is mostly Okay. dev@tsfile.apache.org had a 54% decrease in traffic in the past quarter (60 emails compared to 128)
