这种可以换一下数据库，LeanCloud 有一些场景需要全量拉评论数据下来，对性能影响比较大。

This way, you can change the database. There are some scenarios in LeanCloud that require full comment data to be drawn, which has a great impact on performance.

好的，我把 vercel 的超时时间改成 15s 就可以了，就是量太大了🤦‍♂️

OK, I just need to change the timeout time of vercel to 15s, but the amount is too large🤦‍♂️

今天尝试了一下假如更换数据库的成本，现有评论迁移也是个问题，leanclound导出的数据是jsonl，并不是通用csv，而且还得写脚本处理成对应要迁移的数据库的字段。属实有点麻烦，先这样吧。目前把pagesize设置成5，基本不复现了

Today I tried to try if the cost of replacing the database, existing comment migration is also a problem. The data exported by Leanclound is jsonl, not a general CSSV, and a script has to be written to process it into fields corresponding to the database to be migrated. It's really a bit troublesome, let's do it first. Currently, the pagesize is set to 5, and basically no longer appears
