Preview Release of Apache Flink 2.0

October 23, 2024 - Xintong Song

The Apache Flink community is actively preparing Flink 2.0, the first major release since Flink 1.0 launched 8 years ago. As a significant milestone, Flink 2.0 is set to introduce numerous innovative features and improvements, along with some compatibility-breaking changes. To facilitate early adaptation to these changes for our users and partner projects (e.g., connectors), and to offer a sneak peek into the exciting new features while gathering feedback, we are now providing a preview release of Flink 2.0.

NOTICE: Flink 2.0 Preview is not a stable release and should not be used in production environments. While this preview includes most of the breaking changes planned for Flink 2.0, the final release may still subject to additional modifications.

Breaking Changes #

API #

The following sets of APIs have been completely removed.

DataSet API. Please migrate to DataStream API, or Table API/SQL if applicable. See also How to Migrate from DataSet to DataStream.
Scala DataStream and DataSet API. Please migrate to the Java DataStream API.
SourceFuction, SinkFunction and Sink V1. Please migrate to Source and Sink V2.
TableSoure and TableSink. Please migrate to DynamicTableSource and DynamicTableSink. See also User-defined Sources & Sinks.
TableSchema, TableColumn and Types. Please migrate to Schema, Column and DataTypes respectively.

Some deprecated methods have been removed from DataStream API. See also the list of breaking programming APIs.

Some deprecated fields have been removed from REST API. See also the list of breaking REST APIs.

NOTICE: You may find some of the removed APIs still exist in the code base, usually in a different package. They are for internal usages only and can be changed / removed anytime without notifications. Please DO NOT USE them.

Connector Adaption Plan #

As SourceFunction, SinkFunction and SinkV1 being removed, existing connectors depending on these APIs will not work on the Flink 2.x series. Here’s the plan for adapting the first-party connectors.

A new version of Kafka connector, adapted to the API changes, will be released right after the release of Flink 2.0 Preview.
JDBC and ElasticSearch connectors will be adapted by the formal release of Flink 2.0.
We plan to gradually migrate the remaining first-party connectors within 3 subsequent minor releases (i.e., by Flink 2.3).

Configuration #

Configuration options meet the following criteria are removed. See also the list of removed configuration options.

Annotated as @Public and have been deprecated for at least 2 minor releases.
Annotated as @PublicEvolving and have been deprecated for at least 1 minor releases.

The legacy configuration file flink-conf.yaml is no longer supported. Please use config.yaml with standard YAML format instead. A migration tool is provided to convert a legacy flink-conf.yaml into a new config.yaml. See Migrate from flink-conf.yaml to config.yaml for more details.

Configuration APIs that takes java objects as arguments are removed from StreamExecutionEnvironment and ExecutionConfig. They should now be set via Configuration and ConfigOption. See also the list of breaking programming APIs.

To avoid exposing internal interfaces, User-Defined Functions no longer have full access to ExecutionConfig. Instead, necessary functions such as createSerializer(), getGlobalJobParameters() and isObjectReuseEnabled() can now be accessed from RuntimeContext directly.

Misc #

State Compatibility is not guaranteed between 1.x and 2.x.

Java 8 is no longer supported. The minimum Java version supported by Flink now is Java 11.

Legacy Mode of Hybrid Shuffle is removed.

Highlights of New Features #

Disaggregated State Storage and Management #

The past decade has witnessed a dramatic shift in Flink’s deployment mode, workload patterns, and hardware improvements. We’ve moved from the map-reduce era where workers are computation-storage tightly coupled nodes to a cloud-native world where containerized deployments on Kubernetes become standard. To enable Flink’s Cloud-Native future, we introduce Disaggregated State Storage and Management that uses remote storage as primary storage in Flink 2.0.

This new architecture solves the following challenges brought in the cloud-native era for Flink.

Local Disk Constraints in containerization
Spiky Resource Usage caused by compaction in the current state model
Fast Rescaling for jobs with large states (hundreds of Terabytes)
Light and Fast Checkpoint in a native way

However, simply extending the state store to read/write from remote DFS is insufficient due to the existing blocking execution model in Flink. In Flink 2.0, we propose asynchronous execution model and introduce ForStDB, a disaggregated statebackend solution for this purpose.

In the preview version, we offer a complete end-to-end trial using Nexmark Q20 (SQL Filter Join). This includes:

Asynchronous execution: Full support for asynchronous state APIs and checkpointing.
Asynchronous SQL Join operator: Rewrite SQL Join operators to enable asynchronous join execution.
Hybrid Async & Sync Execution: Hybrid SQL Plan + Runtime Execution + State Access
Performance: Demonstrate performance results directly writing to DFS in async execution mode

Materialized Table #

In Flink 1.20, we introduced Materialized Table as a MVP feature. Materialized Table is an innovative table type in Flink SQL, designed to further streamlining batch and stream data processing while providing a unified development experience. In the upcoming Flink 2.0 release, we are enhancing operational supports for Materialized Tables, including connector integration with cutting-edge lake formats and production-ready schedulers.

Adaptive Batch Execution #

In addition, Flink is continuously enhancing its adaptive batch execution capabilities. The upcoming Flink 2.0 release will introduce dynamic optimization of logical plans, in addition to physical plans, based on insights gained from the execution of previous stages. The initial set of optimization strategies includes the dynamic application of broadcast join and skewed join optimization.

Streaming Lakehouse #

Represented by the integration of Apache Flink and Apache Paimon, the Streaming Lakehouse architecture has extended the unified data storage, open format and cost-effectiveness of the Lakehouse paradigm to the real-time area. The upcoming Flink 2.0 release marks another significant step in enhancing the integration between Flink and Paimon. The Flink and Paimon communities are collaborating closely to adapt to each other’s strengths and fully leverage their cutting-edge features, yielding various improvements including SQL plan optimization utilizing Paimon’s rich merge engines, enhanced bucket-aware lookup join performance, and Paimon support for Flink’s Materialized Table, Adaptive Batch Execution and Speculative Execution.
