Description

我现在有2套 Tdengine 3.2.0.0.0 的集群。分别为 A，B 其中 A 中有60万张子表，整个数据在 1.3G 左右。目前我使用 taosdump 先导出再倒入，由于 A 环境中的数据比较大，就连完整的导出都做不到。经常导着倒着就卡死，同样也试过 RESTFul 的方式。也是一样的效果。 请教一下，是否有还有其他更优的方法处理？

Research direction
Investigate the taosdump source code in the repository to understand limitations. Consider alternative data migration methods such as using the sync module or writing a custom script using TDengine's connector APIs. Check existing documentation and community discussions for known large dataset migration strategies. Report findings or ask maintainers for guidance on the best approach.
