Generate unique IDs in Cassandra

This is real work, not a feature someone invented — it comes from real job ads and real questions people asked. Below are four ready AI prompts: get it done, make it easy for the next person to say yes to, work out the right move when you are stuck, and stop it coming back.

The same task, four prompts

I need to generate a new unique ID for each record being inserted into the 'users' table. Use a UUID version 4 for this.

Before I finalize this data model, I need to ensure that the unique IDs for our 'orders' table are globally unique and collision-resistant, even with high concurrent writes across multiple regions. Also, make sure they are efficient for the database's partitioning strategy.

We're seeing duplicate keys when inserting new sensor readings, even though we're generating UUIDs on the client side.
We're getting duplicate key errors for new sensor readings, even with client-side UUID generation. I'm worried about data corruption and the integrity of our time-series data. I can't tell if it's a clock synchronization issue, a driver problem, or a fundamental misunderstanding of the database's primary key behavior. What's the most likely reason for these duplicates, and what's the best way to ensure true uniqueness for high-volume inserts?

We frequently run into issues with unique ID generation, either with collisions or performance bottlenecks.
I'm tired of the recurring headaches around unique ID generation in our database, whether it's collisions or performance hits under load. We keep patching solutions for specific tables. What habit should I change in how we approach ID generation across our services to ensure reliability, scalability, and ease of use, so I'm not constantly firefighting this issue?

Questions people actually ask

honest answers, no sign-up

Every task here was seen in the real world. Someone doing the job named it, a real job ad asked for it, or a lot of people asked about it online.

If nothing real showed a task, it is not on the page. That is the whole rule.

They are the same job approached four ways, because what you need depends on where you are.

Get it done today. Make it easy for the next person to say yes to. Work out the right move when you are stuck. Learn the pattern so the job stops coming back.

For most of these jobs it can carry the heavy thinking - draft it, sort it, check it, rehearse it with you.

It cannot sit in your chair, take the blame when a number is wrong, or notice what nobody wrote down. Let it do the first 80%. Keep the last 20% that is truly yours.

No. Copy any prompt and paste it into the AI you already use. No account, no score, no wall in the way.

Any of them. The prompts describe the work rather than naming a product, so they are not tied to one assistant.

That is also why they keep working when you switch.

Change it freely. Every prompt is a starting line, not a rule.

Put in your real numbers, your real names and your real deadline. The more you make it yours, the better the answer comes back.

The tasks come from real job ads, published job data and the questions people ask in public forums.

The steps come from Apache Cassandra's own documentation, with practitioner sources for the traps the manual does not mention.

Push once. Ask it to sharpen the weakest part and to say what it assumed.

Most wrong answers come from a missing detail rather than a bad prompt - tell it the thing it could not know.
