Detailed Description
A metadata table backed by a source Iceberg table.
Member Function Documentation
◆ kind()
|
pure virtualnoexcept |
Return this metadata table's kind.
Implemented in iceberg::HistoryTable, iceberg::RefsTable, and iceberg::SnapshotsTable.
◆ MakeScan()
|
protectedpure virtual |
Plan a scan using the captured metadata, projection, and snapshot selection.
Implemented in iceberg::HistoryTable, iceberg::RefsTable, and iceberg::SnapshotsTable.
◆ NewScan()
|
virtual |
Capture the source metadata and create a scan builder.
This metadata table must outlive the builder. Built scans retain their own inputs and can outlive both tables.
◆ schema()
|
pure virtual |
Return the complete canonical schema of this metadata table.
Implemented in iceberg::HistoryTable, iceberg::RefsTable, and iceberg::SnapshotsTable.
