The current solution is excellent. There are a few additional points to note.
1. I suggest adding a pxf-jdbc-drivers documentation page that provides a
verified compatibility
matrix (Database Version × JDBC Driver Version × PXF Version). This would
give users a clear
reference for supported configurations and reduce issues caused by version
mismatches.
2. I suggest adding data type mapping tests for each supported database. The
focus should be on verifying correct read/write behavior for database-specific
types (e.g., Oracle's
NUMBER/DATE/TIMESTAMP WITH TIME ZONE, ClickHouse's
Nullable/LowCardinality/Decimal). A dedicated
type mapping matrix test — with a table covering all special types per
database — would help
catch the most common production issues.
