1. About Apache Linkis

The Apache Linkis computing middleware project was open sourced by WeBank’s big data platform team in July 2019, and officially donated to the world’s top open source community Apache Software Foundation (ASF) in August 2021, becoming an ASF incubation project. Pass the hatch graduation vote on December 03, 2022.

Apache Linkis builds a layer of computing middleware between the upper application and the underlying engine. By using standard interfaces such as REST/JDBC/Shell provided by Linkis, upper-layer applications can easily connect and access lower-level engines such as MySQL/Spark/Hive/Trino/Flink, and at the same time realize cross-upper-layer user resources such as variables, scripts, functions, and resource files Application interoperability, as well as data source management and metadata query services corresponding to data sources are provided through the REST standard interface. As a computing middleware, Linkis provides powerful connectivity, reuse, orchestration, expansion and governance capabilities. The application layer and the engine layer are decoupled through computing middleware, which simplifies the complex network call relationship, reduces the overall complexity, and saves the overall development and maintenance costs.

Since the open source, the total number of users in the open source community group has exceeded 7,600, the sandbox trial companies have exceeded 2,600, and more than 110 companies have received feedback that they have put into production. The data volume supported by the production environment exceeds 400PB, and the number of users of production services exceeds 5,000. , involving finance, telecommunications, manufacturing, Internet and other industries. Many companies have used Linkis to solve computing governance problems such as connectivity, expansion, control, and orchestration of big data platforms.

During the incubation period of more than a year, Apache Linkis has released 7 Apache versions led by community developers, and an average version will be released in about two months; 4 new PPMC members and 13 Committers have been added, from different companies and Team, the number of contributors reached 127. The indicators of the Apache Linkis community are developing well, and the project has matured. Apache Linkis successfully passed the graduation evaluation and voting of the ASF Incubator Project Management Committee, and was approved by the ASF Board of Directors. After graduation, it was promoted to the top project of the Apache Foundation.

2. The core functions of Apache Linkis and Roadmap

By using Linkis, upper-level application tools such as batch systems can use Linkis as a unified gateway or JobServer to submit batch tasks; data analysis tools can use Linkis’ interactive task capabilities to obtain logs, result sets, and progress information in real time. Tools integrated with Linkis can be interconnected, and the same defined UDF, data source, material, etc. can be used in different tools.

The upper-level application tools connected to Linkis can have the following core features:

  • Rich underlying computing and storage engines support:Spark, Hive, Flink, Python, Sqoop, OpenLooKeng, Presto, Trino, ElasticSearch, JDBC, SeaTunnel, Shell, etc.;

  • Rich language support:SparkSQL, HiveQL, Python, Shell, Pyspark, Scala, JSON and JAVA, etc.;

  • Powerful Computing Governance Capabilities:Ability to provide multi-level label-based task routing, load balancing, multi-tenancy, flow control, resource control, etc.;

  • The full-stack computing and storage engine architecture supports:Able to receive, execute and manage tasks and requests for various computing and storage engines, including offline batch tasks, interactive query tasks, real-time streaming tasks and data lake tasks;

  • Unified context service:Support cross-user, system, computing engine to associate and manage user and system resource files (JAR, ZIP, Properties, etc.), result sets, parameter variables, functions, UDF, etc., one setting, everywhere automatic reference;

  • Uniform material:Provides system and user-level material management, which can be shared and transferredshare materials across users and systems;

  • Unified data source management:Provides information addition, deletion and modification, version control, connection testing and metadata information query capabilities for Hive, ElasticSearch, Mysql, Kafka, MongoDB and other types of data sources;

  • Error code capability:Provides error codes and solutions for common errors in tasks, making it easy for users to locate problems by themselves;

Graduating from the incubator also proves that the Linkis project and community have further matured, but there is still a lot to do to become a world-class computing middleware project. The Linkis community has compiled a roadmap, and everyone is welcome to participate and contribute together. Some of the significant features are as follows:

3. Apache Linkis Ecology

Linkis, as a computing middleware, also actively promotes integration with projects in multiple open source communities to enrich Linkis’ ecology. The figure below shows some open source projects that have been integrated with Linkis, covering data analysis, workflow, data exchange, data quality, machine learning, and commonly used computing and storage engines. The upper application tools submit and manage the tasks of various engines through Linkis, and use Linkis as a development base. It greatly reduces the development workload of upper-layer application tools in computing governance such as connectivity, expansion, and control, so that upper-layer application tools only need to focus on their own functional requirements.

In the future, we will further guide and promote more upper-level tool systems and lower-level engines to integrate with Linkis and enrich Linkis’ ecology.More and more projects are welcome to participate in it.

As a heavy user of Apache Linkis, I am very happy to see it graduate from Apache, and I would like to express my sincere blessings here. We started to pay attention to and try to use it in business from 2020, and have migrated most of the underlying business to Linkis for management. In the process, we have received strong support from our community partners and also contributed our own strength. Graduation is not the end, but a new beginning, and there is still a lot of work waiting for us to do. Hope to work with community partners to make Apache Linkis stronger and more perfect in the future.

Apache Linkis is a big data project that was open sourced by WeBank and contributed to the Apache Software Foundation in 2019. Linkis has attracted widespread attention in the industry since it was open sourced. What’s even more commendable is that the developer community formed around the Linkis project is very active. Currently, there are 23 members of the project management committee, 33 code committers and more than 127 contributors. They come from different regions and organizations and spontaneously participate in the project. Develop new features, answer user questions, fix bugs, release versions, etc., showing good diversity and sustainability. In December 2022, the Linkis project passed the Apache incubator’s project maturity assessment and voting, and graduated to become another top Apache project. For Linkis, graduation is not an end, but a milestone. In 2023, I hope that the Linkis community can continue to uphold the concept of The Apache Way, absorb more users and developers with the spirit of Community Over Code, and continue to develop and expand open source software projects so that they can ultimately benefit more businesses and individual users .

It is great to see that the Linkis project donated by WeBank to the Apache Open Source Software Foundation has graduated as a top-level project of the Apache Foundation. This proves that the project sponsors fully understand the values ​​of the Apache Foundation, Community Over Code, and follow the open, transparent, and meritocratic rules of the Apache community for long-term operation. The maturity of the community has been unanimously recognized by the Incubation Committee of the Apache Software Foundation. Congratulations to the Linkis project and team for providing a good project worthy of long-term trust for the big data technology ecosystem. The decoupling of the application layer and the engine layer through computing middleware makes the writing of upper-level big data applications easier and faster.
