             Summary: [RISC-V Support] - Comprehensive Tracking of RISC-V 
Architecture Support in Apache Flink
                 Key: FLINK-38178
                 URL: https://issues.apache.org/jira/browse/FLINK-38178
             Project: Flink
          Issue Type: Improvement
          Components: Build System
            Reporter: Gong Xiaofei


Description: This JIRA serves as an umbrella issue to comprehensively track all 
enhancements, optimizations, and fixes related to enabling and improving 
support for the RISC-V architecture within the Apache Flink project.  The scope 
includes but is not limited to:

1.  Platform-Specific Optimizations and Compatibility Adjustments
Implement architecture-specific optimizations to maximize the performance of 
Flink on RISC-V platforms.
Ensure compatibility of Flink with various RISC-V configurations, including 
different instruction set extensions (e.g., RV64IMUD).
Address any platform-specific issues that arise during the porting process.
2.  Post-Implementation Bug Fixes and Enhancements
Track and address any bugs or performance regressions specific to the RISC-V 
architecture after the initial implementation.
Gather feedback from the community and implement necessary enhancements to 
improve the stability and usability of RISC-V support.
3.  Test and CI Coverage for RISC-V Environments
Develop and integrate comprehensive test cases to validate Flink's 
functionality on RISC-V platforms.
Set up and maintain Continuous Integration (CI) jobs to ensure ongoing 
validation of RISC-V support.
Monitor and resolve any test failures or inconsistencies observed in RISC-V 
environments.
4.  Documentation Updates and UserGuides
Provide detailed documentation to guide users on building, configuring, and 
running Flink on RISC-V based systems.
Include known limitations, best practices, and tuning recommendations for 
RISC-V deployments.
Update the official Apache Flink documentation to reflect the addition of 
RISC-V architecture support.
Key Objective: Ensure that Apache Flink runs efficiently, reliably, and 
seamlessly on RISC-V architectures, achieving full feature parity with existing 
supported architectures.  This includes delivering a consistent user 
experience, maintaining high performance standards, and providing thorough 
documentation.
