> # Abstract
> TsFile is a columnar storage file format designed for time series data,
> which supports efficient compression, high throughput of read and write,
> and compatibility with various frameworks, such as Spark and Flink. It is
> easy to integrate TsFile into IoT big data processing frameworks.
>
> # Proposal
> TsFile is used for managing time series data. 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. In this way, we lower the network transmission and the computing
> resource consumption in the cloud.
>
> # Initial Goals
> The initial goals include:
> Make TsFile an independent project that has its own SDK and documentation
> that is easier to use.
> Multi-Language Support of TsFile implementations apart from Java, such as
> C++, Go and Rust.
> Integrate more encoding and compression methods in TsFile.
> More tools for TsFile: visualization tool, parsing tool, repair tool.
>
> # Current Status
>
> ## Meritocracy
> We plan to invite a subset of the Apache IoTDB committers as initial
> committers of Apache TsFile. And we would like to follow ASF meritocratic
> principles and invite additional developers to participate. We will
> establish the documentation and encourage and monitor community
> participation so that privileges can be extended to those that contribute.
>
> ## Community
> The TsFile community is grown from the Apache IoTDB Community. The IoTDB
> community is introducing TsFile at many technical conferences. Next, we
> will build the mailing list for more convenience, broader communication and
> archived discussions. We are open to recruiting more developers from
> diverse backgrounds.
>
> ## Core Developers
> TsFile initial PMCs are from IoTDB community: Christofer Dutz, Xiangdong
> Huang, Jialin Qiao, Steve Yurong Su, Jinrui Zhang, Yuan Tian, Xinyu Tan,
> Haonan Hou, Gaofei Cao, Tian Jiang, Chao Wang(wangchao316), Chao
> Wang(mychaow), Houliang Qi, Kun Liu.
> These people have extensive experience in building database and data
> management system.
>
> ## Alignment
> The ASF is the natural choice to host the TsFile project as its goal of
> encouraging community-driven open-source projects fits with our vision for
> TsFile. Additionally, many other projects with which we are familiar with
> and expect TsFile to integrate with, such as Apache Spark, Apache Flink and
> Apache IoTDB are hosted by the ASF and we will benefit and provide benefits
> in close proximity to them.
>
> # Known Risks
>
> ## Project Name
> TsFile project is used in IoTDB and other scenarios for over 7 years, its
> name is unique.
>
> ## Orphaned Products
> The core developers plan to work full time on the project. There is very
> little risk of TsFile being abandoned as it is part of Apache IoTDB's
> internal infrastructure. Tsinghua and NEL-BDS Lab relies on TsFile as a
> platform for many long-term research projects. Companies such as Timcho,
> Huawei, BONC, Yonyou will also participate in this project.
>
> ## Inexperience with Open Source
> All of the core developers have experience with open-source development.
> We have 1 Apache Board member(Christofer Dutz), 2 Apache Members(Xiangdong
> Huang, Jialin Qiao) and 11 Apache IoTDB PMCs in TsFile initial PMCs. We
> have the experience of the Apache way, such as community over code, license
> management, version release, CEV processing, attract committer/pmcs and
> meetups.
>
> ## Length of Incubation
> There are enough initial PMCs of TsFile know the ASF process well, so we
> apply to go straight to TLP.
>
> ## Homogeneous Developers
> The current core developers are from diverse groups: Apache IoTDB
> Community, Timecho, BONC, Huawei, eBay, Yonyou and Tsinghua University.
>
> ## Reliance on Salaried Developers
> Currently, the developers are paid to do work at Timecho, BONC, Huawei and
> Tsinghua University. Also, we have students and researchers/professors
> community in universities, and their researches focus on big data
> management and analytics. It is unlikely that they will change their
> research focus away from big data management. We will work to ensure that
> the ability for the project to continuously be stewarded and to proceed
> forward independent of salaried developers is continued.
>
> ## Relationships with Other Apache Products
> TsFile is used by Apache IoTDB project as the default data file format.
> TsFile-Spark-connector and TsFile-Flink-connector have been developed to
> support analyzing time series data by using Apache Spark and Flink.
> Overall, TsFile is designed as an open architecture, and it can be
> integrated with many other systems in the future.
>
> ## An Excessive Fascination with the Apache Brand
> We respect the reputation of the Apache brand and have no doubt that it
> will attract contributors and users. Most of the initial developers come
> from Apache IoTDB Community, so we have no intent to use the Apache brand
> for profit. Our goal is making TsFile integrating more with Apache projects
> and letting Apache community more professional in IoT data management.
