Example 1 with FORMAT_FIELDS

use of org.apache.flink.table.descriptors.OldCsvValidator.FORMAT_FIELDS in project flink by apache.

the class CsvTableSinkFactoryBase method createTableSink.

protected CsvTableSink createTableSink(Boolean isStreaming, Map<String, String> properties) {
    DescriptorProperties params = new DescriptorProperties();
    params.putProperties(properties);
    // validate
    new FileSystemValidator().validate(params);
    new OldCsvValidator().validate(params);
    new SchemaValidator(isStreaming, false, false).validate(params);
    // build
    TableSchema tableSchema = TableSchemaUtils.getPhysicalSchema(params.getTableSchema(SCHEMA));
    // if a schema is defined, no matter derive schema is set or not, will use the defined
    // schema
    final boolean hasSchema = params.hasPrefix(FORMAT_FIELDS);
    if (hasSchema) {
        TableSchema formatSchema = params.getTableSchema(FORMAT_FIELDS);
        if (!getFieldLogicalTypes(formatSchema).equals(getFieldLogicalTypes(tableSchema))) {
            throw new TableException(String.format("Encodings that differ from the schema are not supported yet for" + " CsvTableSink, format schema is '%s', but table schema is '%s'.", formatSchema, tableSchema));
        }
    }
    String path = params.getString(CONNECTOR_PATH);
    String fieldDelimiter = params.getOptionalString(FORMAT_FIELD_DELIMITER).orElse(",");
    Optional<String> writeModeParam = params.getOptionalString(FORMAT_WRITE_MODE);
    FileSystem.WriteMode writeMode = (writeModeParam.isPresent()) ? FileSystem.WriteMode.valueOf(writeModeParam.get()) : null;
    int numFiles = params.getOptionalInt(FORMAT_NUM_FILES).orElse(-1);
    // bridge to java.sql.Timestamp/Time/Date
    DataType[] dataTypes = Arrays.stream(tableSchema.getFieldDataTypes()).map(dt -> {
        switch(dt.getLogicalType().getTypeRoot()) {
            case TIMESTAMP_WITHOUT_TIME_ZONE:
