## TL;DR

[zilliztech/zilliz-plugin developer guide]: dimension mismatch means the vector size does not match the collection, check len(vector) against the collection dimension. node not match means cluster scaling is in progress, wait a few seconds and retry with backoff. collection not found means a wrong name or it was never created, check list_collections. rate limit exceeded means too many requests, implement backoff and check quotas.

## Steps

1. [zilliztech/zilliz-plugin developer guide]: dimension mismatch means the vector size does not match the collection, check len(vector) against the collection dimension. node not match means cluster scaling is in progress, wait a few seconds and retry with backoff. collection not found means a wrong name or it was never created, check list_collections. rate limit exceeded means too many requests, implement backoff and check quotas. For cold-start search latency, call load_collection first; insert bottlenecks go away with batch_size 5000.

## When to use

You are seeing this: For cold-start search latency, call load_collection first; insert bottlenecks go away with batch_size 5000. Use this skill when you run into "Zilliz Cloud: dimension mismatch and other common error diagnostics".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

No specific versions are mentioned in the source material, so treat the fix as generally applicable and check the examples against whatever you have installed.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
