问题提出

数据不断写入iceberg, 也进行合并与清理快照，发现快照和manifest文件都被清理，但metadata的文件没有被清理的痕迹

数据文件只有6.3M,数据个数20个，但metadata总大小33.1G，metadata个数8715个， 清理最后一个快照前5分钟的所有数据，发现对数据没影响

问题解决方法？ 待后续解决，关注后面更新。。。

出现问题的建表方式

基于hiveCatalog在sqlClient建表，建表语句，具体查看11课。
在第11课结尾中也发现这个问题。单独写一篇文章以显示它的重要性。

iceberg小文件合并后出现的问题（现状）

iceberg的文件合并与快照删除特点：

合并：会生成新的文件
快照删除：会删除snap和Manifests 文件，metadata文件没有合并，并清理老metadata
