Does spark DataFrame.limit guarantees any order?

This is just a question, not an issue.
Out of curiosity, does spark.DataFrame.limit guarantees the order ?

That method is used to implement many methods like .head, .iloc
In pandas the data is small and the order could be guaranteed. But in koalas, the data is distributed. Is it guaranteed those methods would keep order?

Yes, it’s a bit questionable at this moment. Maybe we should do one of these: …

1. We just disallow all such cases
2. Document the case when the order can be deterministic
3. Document that the index always should be sorted before such operations for order guarantee
4. Internally always sort on the index before such operations in such cases

Yes, that’s correct 😃.
