### Search before asking - [X] I searched in the [issues](https://github.com/apache/incubator-paimon/issues) and found nothing similar. ### Motivation Position delete is a solution to implement the Merge-On-Read (MOR) structure, which has been adopted by other formats such as Iceberg and Delta. By combining with Paimon's LSM tree, we can create a new position deletion mode unique to Paimon. Under this mode, extra overhead (lookup and write delete file) will be introduced during writing, but during reading, data can be directly retrieved using "data + filter with position delete", avoiding additional merge costs between different files. Furthermore, this mode can be easily integrated into native engine solutions like Spark + Gluten in the future, thereby significantly enhancing read performance.
