Caracal is a shared-memory, batch-based, multi-version deterministic concurrency control protocol that efficiently handles contention. In the initialization phase, Caracal appends pending versions of the same data item from the same core simultaneously using dynamically allocated buffers when contention occurs. The problem of Caracal is that lock acquisition is still required when performing shared-memory write on the global version array, which is particularly evident in write-intensive workloads. This paper introduces Serval, a novel method aimed at improving upon Caracal's limitations. Serval utilizes sequential assignment to assign transactions instead of the round-robin method, adopts per-core version array, and incorporates 2 types of bitmaps to indicate the information of update operation. By leveraging these enhancements, Serval ensures lock-free and no-remote write conditions during the initialization phase and provides more efficiency in the execution phase under contention. |
