使用 Apache Ignite 进行 Flyway

Question

有人可以告诉我如何将 Flyway 与 Apache Ignite 集成吗？我在 Flyway 文档中找到了 Maven 依赖项，但找不到“INFORMATION_SCHEMA”。 造成这种情况的原因是什么以及我该如何解决它？ 也许有更方便的迁移方式。 主要思想是如果最近没有应用它们，则在应用程序启动时执行 sql 脚本。

<dependency>
            <groupId>org.flywaydb</groupId>
            <artifactId>flyway-core</artifactId>
            <version>10.12.0</version>
        </dependency>
        <dependency>
            <groupId>org.flywaydb</groupId>
            <artifactId>flyway-database-ignite</artifactId>
            <version>10.12.0</version>
        </dependency>

Ignite 已经有一段时间没有

INFORMATION_SCHEMA

了。大多数相同的信息都在 SYS 模式中，但使用它需要在 Flyway 中进行一些代码更改。
