Although it is firstly used > inside IoTDB, many users and companies use TsFile directly as a time series > data management solution independently. Besides, there is a growing > requirement for Multi-Language Support of TsFile implementations, such as > C++, Go and Rust. > > Apache IoTDB community hereby submit this proposal of TsFile as an > independent Apache project. This proposal outlines the key features and > benefits of TsFile, along with the integration plan and the need for > multi-language support. > > # Background > Time series data is becoming increasingly important in a wide range of > applications, including IoT, intelligent control, finance, log analysis, > and monitoring systems. > TsFile has been developed by the Apache IoTDB community in Java and is > currently located inside the Apache IoTDB code repository. Users could > store time series data using TsFile, then read and analyze it in IoTDB, > Spark and Flink. IoTDB could also generate TsFiles and synchronize TsFiles > between two IoTDB instances. > Furthermore, the demand for TsFile implementations in multiple programming > languages has been growing, as it allows developers to leverage TsFile's > capabilities in their preferred language. > > # TsFile offers several distinctive features and benefits: > Efficient Storage and Compression: TsFile employs advanced compression > techniques to minimize storage requirements, resulting in reduced disk > space consumption and improved system efficiency. > Flexible Schema and Metadata Management: TsFile allows for directly write > data without predefining the schema, which is flexible for data acquisition. > High Query Performance with time range: TsFile has indexed devices, > sensors, and time dimensions to accelerate query performance, enabling fast > filtering and retrieval of time series data. > Seamless Integration: TsFile is designed to seamlessly integrate with > existing big data frameworks, such as Spark, Flink and Hadoop. > > # Rationale > TsFile is the first existing standard file format for time series data. In > the industry companies usually write time series data without unification > or use general columnar file format such as Parquet and ORC, which makes > data collection and processing complicated without a standard. With TsFile, > organizations could write data in TsFile inside end devices or gateway, > then transfer TsFile to the cloud for unified management in IoTDB and other > systems.

Tsinghua and NEL-BDS Lab relies on TsFile as a > platform for many long-term research projects.
