How to generate a workload trace file, such as : ycsb-c-1m?

[qxzhou1010]

I'm studying another open source project and they use YCSB. It is mentioned in the documentation of this project that we need to download a ycsb-c-1m file. The relevant content is:

Download one of our workload traces from s3 and place it into the root of pancake's directory.

aws s3 --no-sign-request cp s3://pancaketranscripts/ycsb-c-1m .

However, the s3 bucket no longer exists, so I cannot download the ycsb-c-1m file. This prevents me from getting the project running.

After some exploration, I found the open source project YCSB. However, I still don't know how to generate such a ycsb-c-1m.
Please help me, please tell me how to generate such a workload traces ycsb-c-1m.
