Apache Calcite 1.16.0 发布，动态数据管理框架

Linuxeden 开源社区 --

Apache Calcite 1.16.0 已发布，Apache Calcite 是一个动态数据管理框架，用于 Hadoop 平台。

此版本在 1.15.0 之后三个月发布。它解决了 80 多个已知的问题，包括大量的新功能以及对 Calcite 核心的一般改进和缺陷修复。

更新内容：

• Calcite has been upgraded to use Avatica 1.11.0, which was recently released.
• Moreover, a new adapter to read data from Apache Geode was added in this release. In addition, more progress has been made for the existing adapters, e.g., the Druid adapter can generate SCAN queries rather than SELECT queries for more efficient execution and it can push more work to Druid using its new expressions capabilities, and the JDBC adapter now supports the SQL dialect used by Jethro Data.
• Finally, this release drops support for JDK 1.7 and support for Guava versions earlier than 19.
