TableScanNode

private TableScanNode(Compiler compiler,

                      Enumerable<Row> enumerable)

create

static TableScanNode create(Compiler compiler,
                            TableScan rel,
                            com.google.common.collect.ImmutableList<RexNode> filters,
                            ImmutableIntList projects)

Creates a TableScanNode.

Tries various table SPIs, and negotiates with the table which filters and projects it can implement. Adds to the Enumerable implementations of any filters and projects that cannot be implemented by the table.

createScannable

private static TableScanNode createScannable(Compiler compiler,
                                             TableScan rel,
                                             com.google.common.collect.ImmutableList<RexNode> filters,

                                             ScannableTable scannableTable)

createQueryable

private static TableScanNode createQueryable(Compiler compiler,
                                             TableScan rel,
                                             com.google.common.collect.ImmutableList<RexNode> filters,
