Push Down Filter Across Multiple Data Sources

[Bahareh Nikfarjam]

Hello,

I am trying to use calcite to query across two databases. I have a query
that joins between table1 in DB1 and table2 in DB2. there is a filter on
table2. Is there a way in calcite to push down the filter on table 2 to the
source database?

Thanks,
Bahareh
