Examples with SYNTHESIZED io.trino.plugin.deltalake.DeltaLakeColumnType.SYNTHESIZED used on opensource projects

Example 1 with SYNTHESIZED

use of io.trino.plugin.deltalake.DeltaLakeColumnType.SYNTHESIZED in project trino by trinodb.

the class DeltaLakeMetadata method getTableHandleForOptimize.

private Optional<ConnectorTableExecuteHandle> getTableHandleForOptimize(DeltaLakeTableHandle tableHandle, Map<String, Object> executeProperties) {
    DataSize maxScannedFileSize = (DataSize) executeProperties.get("file_size_threshold");
    List<DeltaLakeColumnHandle> columns = getColumns(tableHandle.getMetadataEntry()).stream().filter(column -> column.getColumnType() != SYNTHESIZED).collect(toImmutableList());
    return Optional.of(new DeltaLakeTableExecuteHandle(tableHandle.getSchemaTableName(), OPTIMIZE, new DeltaTableOptimizeHandle(tableHandle.getMetadataEntry(), columns, tableHandle.getMetadataEntry().getOriginalPartitionColumns(), maxScannedFileSize, Optional.empty()), tableHandle.getLocation()));
}

Example 2 with SYNTHESIZED

use of io.trino.plugin.deltalake.DeltaLakeColumnType.SYNTHESIZED in project trino by trinodb.

the class DeltaLakeMetadata method getUpdateRowIdColumnHandle.

// The rowId is a RowType where the first field is a BigInt containing the row number. The second field contains the values of any columns that were unmodified.
// They are needed to write the complete row after modifications in DeltaLakeUpdatablePageSource. If there are no unmodified columns, the rowId only has one field.
@Override
public ColumnHandle getUpdateRowIdColumnHandle(ConnectorSession session, ConnectorTableHandle tableHandle, List<ColumnHandle> updatedColumns) {
    DeltaLakeTableHandle handle = (DeltaLakeTableHandle) tableHandle;
    List<DeltaLakeColumnHandle> unmodifiedColumns = getUnmodifiedColumns(handle, updatedColumns);
    Type rowIdType;
    if (unmodifiedColumns.isEmpty()) {
        rowIdType = RowType.rowType(RowType.field(BIGINT));
    } else {
        List<RowType.Field> unmodifiedColumnFields = unmodifiedColumns.stream().map(columnMetadata -> RowType.field(columnMetadata.getName(), columnMetadata.getType())).collect(toImmutableList());
        rowIdType = RowType.rowType(RowType.field(BIGINT), RowType.field(RowType.from(unmodifiedColumnFields)));
    }
    return new DeltaLakeColumnHandle(ROW_ID_COLUMN_NAME, rowIdType, SYNTHESIZED);
