JDBC with hints

Hi all,

we are looking for a way to pass parameters [0] through Calcite to HANA using JDBC. We thought that using hints might be a good idea. Unfortunately, hints are not passed to JdbcTableScan in JdbcTable.toRel.
These are my questions:
1. Do you think hints are the correct way to pass parameters to HANA?
2. Would a PR be appreciated to forward hints to JDBC and let the SqlDialect decide how to handle them?
