是否有ANTLR格式的openGauss SQL与PL/pgSQL词法语法
by 刘江山
18 Apr '23
18 Apr '23
您好!我们想基于ANTLR解析器生成工具对openGauss做些外部工具的开发,查看了ANTLR在Github上的语法仓库
https://github.com/antlr/grammars-v4/tree/master/sql
主流的开源数据库基本上都维护了ANTLR格式的文法以扩充其拓展性,请问openGauss是否现有ANTLR格式文法可供使用,或是否考虑支持ANTLR格式的文法? 谢谢! 刘江山 天津大学智能与计算学部 软件分析与智能实验室 邮箱:jiangshan.liu(a)tju.edu.cn

评审结论详情:https://etherpad.opengauss.org/p/Tools-meetings
议题申报: 议题1:设计文档评审(主讲人:王正元) 【迁移工具】迁移工具可调试性增强、可靠性增强(增量迁移) 【迁移工具】迁移工具可调试性增强、可靠性增强(反向迁移) 议题2:⽀持在switchover超时时,打印数据库内核的堆栈设计方案评审(移动 Jenny) 评审意见: 议题1:设计文档评审(主讲人:王正元) 【迁移工具】迁移工具可调试性增强、可靠性增强(增量迁移) 【迁移工具】迁移工具可调试性增强、可靠性增强(反向迁移) 1、迁移失败的数据直接展示sql语句 2、进度上报功能作为公共接口,在具体模块实现,设计类之间的实现与交互关系 3、文件输出路径应该在工具的工作目录下,保证权限最小化 4、历史进度文件按文件数和时间定点清理 5、工具应支持自主上报总体数据时延 6、进度数据各字段命名要尽量见名知义 7、进度文件应支持覆盖写入和追加写入两种形式 8、source端配置黑名单是有跳过的数据,进度文件应该包含该字段 9、配置文件添加功能开关参数 10、允许新功能对迁移性能的影响在合理范围内 11、调研进度是否可根据数据存储量大小上报 12、后续反向断点续传注意数据一致性 议题2:⽀持在switchover超时时,打印数据库内核的堆栈设计方案评审(移动 Jenny) 该议题主要涉及存储层修改,建议该议题在存储sig进行评审 Thanks & Best regards! ________________________________ 窦欣 (Dou Xin) E-mail: douxin5(a)huawei.com<mailto:douxin5@huawei.com> Department: openGauss Program
