    • copy

      public ClickHouseRecord copy()
      Description copied from interface: ClickHouseRecord
      Creates a new record by copying values from current one.
      Specified by:
      copy in interface ClickHouseRecord
      Returns:

    • getValue

      public ClickHouseValue getValue(int index)
      Description copied from interface: ClickHouseRecord
      Gets deserialized value wrapped in an object using column index. Please avoid to cache the wrapper object, as it's reused among records for memory efficiency when ClickHouseDataConfig.isReuseValueWrapper() returns true, which is the default value. So instead of map.put("my_value", record.getValue(0)), try something like map.put("my_value", record.getValue(0).asString()).
      Specified by:
      getValue in interface ClickHouseRecord
      Parameters:
      index - zero-based index of the column
      Returns:
      non-null wrapped value

    • getValue

      public ClickHouseValue getValue(String name)
      Description copied from interface: ClickHouseRecord
      Gets deserialized value wrapped in an object using case-insensitive column name, which usually is slower than ClickHouseRecord.getValue(int). Please avoid to cache the wrapper object, as it's reused among records for memory efficiency when ClickHouseDataConfig.isReuseValueWrapper() returns true, which is the default value. So instead of map.put("my_value", record.getValue("my_column")), try something like map.put("my_value", record.getValue("my_column").asString()).
      Specified by:
      getValue in interface ClickHouseRecord
      Parameters:
      name - case-insensitive name of the column
      Returns:
      non-null wrapped value

    • size

      public int size()
      Description copied from interface: ClickHouseRecord
      Gets size of the record.
      Specified by:
      size in interface ClickHouseRecord
      Returns:
      size of the record
