Motivation

Now, our auto create partition machanism will create may partitions at one point time which may bring mich pressure at one time. We should introduce a jitter so that different tables may create table at different time point to reduce the presure.

Now, 12 tables, 512 bucket per partition, at around 0:10, Fluss with create them, then the isr changes quickly, in bytes decrease, and metrics will looks like:

Solution

We can introduce jitter to alleviate it first.. But we still need to figure out why it cause isr changes quickly.
