> Awesome! Could you please share some information about the architecture of the new solution? I think there might be an original (acmsigmod?) article on how to build an effective interconnect layer. (I see some familiar elements in the code, but I cannot fully comprehend what it is) During performance testing, we identified the Motion node as a significant performance bottleneck. Further analysis revealed that the root cause stems from inefficiencies in the underlying IPC layer protocol implementation. To address this, we plan to enhance the IPC layer to improve overall system performance. Currently, the IPC layer is tightly coupled with the database kernel, which makes implementing performance optimizations challenging and limits flexibility. As an initial step, we are decoupling the IPC layer from the database kernel. This separation will not only simplify future improvements but also enable independent testing and development of the IPC layer. This commit represents foundational work—specifically, the decoupling of the existing UDP-based IPC layer from the database kernel—and lays the groundwork for subsequent performance optimization efforts. -- This is an automated message from the Apache Git Service.
