Limitations and open questions
- 未实测；未安装 Java/Maven 依赖、编译或读写 Parquet 文件。
- 此条记录 Java 实现库；不能把 Parquet 格式规范本身当作可执行服务。
- 构建要求来自当前仓库 README；未独立确认每个旧发行版的 Java 兼容矩阵或所有可选编码/加密功能。
- Read-only directory tools do not imply downstream interfaces are read-only or safe for every operation.
- 独立主来源复核只支持本记录列明的文档事实及明确的编辑分类；未验证任何安装、真实部署、凭据、业务调用或商业权益。已读与未读来源的逐字段范围见独立来源回执，不将其余链接自动视作已复核。
- authentication.required=false 仅描述所选本地库/本地文件工作流没有统一厂商服务账户前提，是有范围的编辑判断；不免除目标网站、远程存储、远程浏览器、操作系统、文件或进程权限。
- 保留官方仓库所述 Java/Parquet 读写形态与文档版本 1.18.1；Java17+ 是该次 README 的构建要求，不是所有历史发行或目标运行环境已验证。
- 代码 LICENSE 链接仍留在 evidence，语义是软件许可材料，不是托管/支持/RPA/运维价目表，也不是相关网页、协议规范或第三方依赖的完整复用授权。
An unlisted MCP, API or CLI means this directory has no reviewed record. It does not establish that the vendor has no such interface.
