where clause in presto cutom connector

Question

I have written a custom connector for presto for which I now need to provide the support for "where" clause so that I can pass that information further to the REST Endpoint(Data Source) so that I get filtered results only.

Let me know if anyone knows how to access this information(from which object) so I can fulfill the above use case.

Any help/hint will be highly appreciated.

Thanks, Dheeraj

To handle the where clause, you need to provide the implementation for getSplits method of ConnectorSplitManager. You can get the constraints from ConnectorTableLayoutHandle object and fetch the corresponding splits.
