Question

我正在使用Liquibase maven插件的generateChangeLog目标来生成目标数据库的完整更改日志。但是，目前我需要为导出的数据部分排除一些表，因为它们包含太多数据而且我得到OutOfMemory例外。

是否可以使用diffExcludeObjects或diffIncludeObjects仅排除/包含更改日志数据部分的表，同时使用ddl部分的所有表？

我尝试将run分成三个单独的执行，它们使用以下diffTypes

表，视图，列，primarykeys
数据
foreignkeys，uniqueconstraints，索引

然而，当我这样做时，我面临以下错误。

您可能只是尝试增加提供给Liquibase JVM的内存并将其保留在一次运行中。

Liquibase generateChangeLog - 如何排除某些数据并将所有ddl更改日志保留为单次执行？
