Comparison of Cross‑Node Join Queries Between DBLE and Mycat Middleware

This article presents a step‑by‑step comparison of DBLE and Mycat distributed middleware by setting up a test environment, defining table schemas and sharding rules, inserting sample data, executing the same cross‑node join query on both systems, and analyzing the differing results and execution plans to explain why Mycat omits expected rows while DBLE returns the correct result.
