Example 1 with TableauStyle

use of org.apache.flink.table.utils.print.TableauStyle in project flink by apache.

the class CliTableauResultView method printStreamingResults.

private void printStreamingResults(AtomicInteger receivedRowCount) {
    TableauStyle style = PrintStyle.tableauWithTypeInferredColumnWidths(resultDescriptor.getResultSchema(), resultDescriptor.getRowDataStringConverter(), resultDescriptor.maxColumnWidth(), false, true);
    // print filed names

    style.printBorderLine(terminal.writer());
    terminal.flush();
    while (true) {
        final TypedResult<List<RowData>> result = sqlExecutor.retrieveResultChanges(sessionId, resultDescriptor.getResultId());
        switch(result.getType()) {
            case EMPTY:

Example 2 with TableauStyle

use of org.apache.flink.table.utils.print.TableauStyle in project flink by apache.

the class CliTableauResultView method printBatchResults.

private void printBatchResults(AtomicInteger receivedRowCount) {
    final List<RowData> resultRows = waitBatchResults();
    receivedRowCount.addAndGet(resultRows.size());
    TableauStyle style = PrintStyle.tableauWithDataInferredColumnWidths(resultDescriptor.getResultSchema(), resultDescriptor.getRowDataStringConverter(), PrintStyle.DEFAULT_MAX_COLUMN_WIDTH, false, false);
    style.print(resultRows.iterator(), terminal.writer());
