Do we need to publish `arrow-integration-test` to crates.io?

[Jefffrey]

It seems odd that in our list of crates to publish, we see that crate:

arrow-rs/dev/release/README.md

Lines 214 to 240 in 12091af

	```shell
	(cd arrow-buffer && cargo publish)
	(cd arrow-schema && cargo publish)
	(cd arrow-data && cargo publish)
	(cd arrow-array && cargo publish)
	(cd arrow-select && cargo publish)
	(cd arrow-ord && cargo publish)
	(cd arrow-cast && cargo publish)

https://crates.io/crates/arrow-integration-test/59.1.0 🤔

Indeed we have documentation & discussion that its meant only for internal use:

• Document limitations of the arrow_integration_test crate #8738

It seems its only usage is in arrow-integration-testing, but this is already via a local dependency and this crate is not published either

arrow-rs/arrow-integration-testing/Cargo.toml

Line 40 in 12091af

arrow-integration-test = { path = "../arrow-integration-test", default-features = false }

Can we stop publishing this crate if it is not meant to be external?

How about we try and not publish it and see if anyone is using it 🤔 I don't remember any reason it is published

[tustvold]

IIRC we split this out from arrow proper and got feedback that someone was using it, so we started publishing it. There's probably an issue about it

[Jefffrey]

Ah yeah found it:

• Split out arrow-integration-test crate #2868

Also it seems we have a bug issue raised for the crate:

• field_to_json() in arrow_integration_test/ field.rs does not serialize fields metadata #6700

So I guess it is somewhat in use

[alamb]

👍 I will keep publishig it then
