Sounds a bit like a bug to be honest. OTOH, for things like Arrow we can't know if the column is all the way null without getting all the output which is kind of a thing we'd like to avoid.

What about cbor and smile?

@nik9000 - Good catch! It does look like cbor and smile contains all_columns within the output, while (as you suspected) arrow does not. With this in mind, I'm going to make an update to this doc which notes the formats that are supported for both human readable and binary.

Given that this sounds like a bug, would you recommend I open up an associated issue to track if the other human readable options, such as csv, tsv, & txt has the same sort of limitations as arrow or if we are running into a bug?

@nik9000 are you happy to merge this docs PR?

ℹ️ What's happening?

• Starting January 29, we will start closing all unmerged documentation PRs targeting main/master
• We're migrating from AsciiDoc to Markdown for 9.0+
• 9.0 docs will be frozen from January 29 until February 20 2024
• NOTE: PRs that include both code and documentation changes will remain open

What do I need to do?

For <=8.x docs:

1. Rebase your PR to target the relevant 8.x branch instead
2. The content can remain in AsciiDoc format

For 9.0+ docs:

Option 1:

• Draft docs in Markdown
• Once migration freeze ends, find the relevant page in the new docs system and use the edit options to submit your changes

Option 2:

• Open an issue in elastic/docs-content

Ah! We've fixed drop_null_columns to work in text response formats.
