GH-110: Flight SQL JDBC related StringView components implementation

[ViggoC]

What's Changed

Flight SQL JDBC related StringView components implementation.

Closes#110.

[ViggoC]

@lidavidm I have drafted something; could you help me determine if I am on the right track? Currently, all the tests are being modified in-place, and I plan to refine them further. Do you think there are additional tests I should include?

[lidavidm]

Looks reasonable to me.

[lewiszlw]

Thanks for your implementation! Our project is being blocked by this. What help I can provide so this pr can be merged soon?

[ViggoC]

@lewiszlw It's ready for review now.

[lewiszlw]

I build jdbc driver package from your branch and tested it in our project, but got error Unsupported vector type: org.apache.arrow.driver.jdbc.shaded.org.apache.arrow.vector.ViewVarBinaryVector. @ViggoC

[ViggoC]

could you share the stack? @lewiszlw

[lewiszlw]

could you share the stack? @lewiszlw

Our stack is rust built server based on Datafusion query engine, and expose flight sql api. Our clients are Java stack.

I used dbevaer software to verify your branch.

@lewiszlw
From your error message, I can confirm it's because ArrowFlightJdbcAccessor doesn't support StringView. But I'm not familiar with Flight JDBC, so I'm not sure how much work still need to fully support StringView. I need to first build an end-to-end test to confirm which parts are not yet supported.

[lewiszlw]

I sent a pr to your branch. I'm testing it. Note that I can only test binary view type. @ViggoC

[ViggoC]

@lewiszlw Given that you have a real usage environment, it would be great if you are willing to make the fixes.

[lewiszlw]

I've sent a pr to your branch ViggoC#1. @ViggoC

[lewiszlw]

I tested this pr in our project.

JNI failures are unrelated.
