Your prompt

Help me defuse hot keys in database and cache.
System: [System]
Pattern: [Pattern]
Symptom: [Symptom]
Steps: 1. Read access counts per key or partition. 2. Flag keys with far more load than the median. 3. Explain the cause: counter, popular record, poor partition key. 4. Propose spreading: suffix sharding, local cache, batched counters. 5. Name what consistency is lost. 6. Write measurement points and a load test.
Output: hot-key list, cause, spreading options, consistency note and load test.

Take particular care to spread load away from single keys and state the consistency cost openly.

Before you answer, check: Are all instructions met? If key information is missing or a placeholder in square brackets is still in the text, ask instead of guessing. Mark assumptions as assumptions.

This is an instruction for an AI, not the result itself.

Where this prompt works

These AI tools are a good fit for this prompt:

How to use it

Fill in the fields or tap a suggestion. Leave out names, addresses and other personal data.
Copy the finished prompt into an AI tool of your choice.
Paste access counts per key or partition as aggregates, without customer data.

Why does this work?

More nodes do not help when every request targets the same key. Spread the key first, then scale.

Tips

Check whether a counter truly must be exact right away; often a value merged every few seconds is enough.
