Igor Suhorukov updated ARROW-17631:
-----------------------------------
Description: Allow user to provide comment in Arrow Schema from
JdbcToArrowConfig . It will be very useful metadata in real life (medium to
large scale project) for documentation and maintenance topics. Apache Spark
code use "comment" key for such metadata, so this looks like reasonable default
name for metadata in Arrow schema too (was: Allow user to provide comment in
Arrow Schema from custom comment handler(or constant values from configuration)
in JdbcToArrowConfig . It will be very useful metadata in real life (medium to
large scale project) for documentation and maintenance topics. Apache Spark
code use "comment" key for such metadata, so this looks like reasonable default
name for metadata in Arrow schema too)
