Description

I noticed that the ADBC metadata information assumes a fixed hierarchy:
https://github.com/apache/arrow-adbc/blob/2485d7c3da217a7190f86128d769a7d0445755ab/java/core/src/main/java/org/apache/arrow/adbc/core/AdbcConnection.java#L58

What would the advice be for datasources that don't fit this, like Snowflake/Trino/Dremio where the hierarchy might be:
- `datasource.database.schema.table`
- `postgres1.mydb.public.emps`
