--------------------------------
> The current default value of avg_series_point_number_threshold has a great
> impact on the write performance of aligned timeseries

> 周测场景，关合并，对齐序列，顺序数据
> 对比# avg_series_point_number_threshold=100000最新默认值
> 与原默认值# avg_series_point_number_threshold=10000
> 的写入性能（最新默认值100000对写入性能影响大）
> !screenshot-2.png!
> !screenshot-1.png!
> avg_series_point_number_threshold=100000 数据库有system reject
> （部分写入失败failOperation=30，okOperation=499970）
> avg_series_point_number_threshold=10000数据库没有system reject，全部写入成功。
> 测试机器192.168.10.64 72C256G，本地测试。
