描述

Specifically, tune the ParallelBatchCommits constant added in #4296. Right now, we just use NumCPU*2 but we could probably do something fancier (learn it? does the datastore matter? does the storage medium matter? how about the filesystem?).

We may never get to this but hey, if anyone wants to spend some time experimenting they're free to take a crack at it.

研究方向
Investigate the `ParallelBatchCommits` constant added in #4296. Experiment with different values and measure performance across various datastores, storage media, and filesystems. Consider implementing adaptive tuning based on runtime metrics. Refer to the codebase for how the constant is used in batch add operations.
