> Key: CALCITE-1515
> URL: https://issues.apache.org/jira/browse/CALCITE-1515
> Project: Calcite
> Issue Type: Bug
> Affects Versions: 1.10.0
> Reporter: Anton Mushin
> Assignee: Julian Hyde
> Priority: Minor
>
> Calcite has a TableFunctionScan, which is a RelNode, takes a function, 0 or
> more RelNode inputs, and 0 or more other arguments.
> RelBuilder does not support TableFunctionScan yet.
> add In RelBuilder TableFunctionScanFactory which will create
> LogicalTableFunctionScan like as for LogicalTableScan and factory for others
> RelNodes [
> [example|https://github.com/apache/calcite/blob/master/core/src/main/java/org/apache/calcite/tools/RelBuilder.java#L125]
> ]
> also adding a functionScan method, analogous to the scan method but for table
> functions.
