Re: Enhancing MVCC ReadView Scalability
The first major improvement is the enhancement of the MVCC ReadView data structure.
Performance comparison tests were conducted to evaluate the effectiveness of the MVCC ReadView optimization. The figure below shows a comparison of TPC-C throughput with varying concurrency levels, before and after modifying the MVCC ReadView data structure.
The second major improvement we made is addressing the double latch problem, where "double latch" refers to the requirement for the global trx-sys latch by both view_open and view_close service.
