[Technical Analysis of the Loser Tree Algorithm for Multi-way Merge.pdf](https://github.com/user-attachments/files/26394582/Technical.Analysis.of.the.Loser.Tree.Algorithm.for.Multi-way.Merge.pdf) First of all, sorry for the late reply. The above is the algorithm details regarding the loser tree-based multi-way merge sort. It should be noted here that during practice, we found that we need to perform local deduplication on each batch of data during the writing process. This has two advantages: 1. first, there is no need to perform the heavy clone operation on each piece of data during multi-way merging; 2. second, deduplication during writing eliminates the need for each reader to repeatedly bear the pressure of deduplication. -- This is an automated message from the Apache Git Service.
