• To avoid conflict with the new LogRecord class, rename existing sdk::logs::LogRecord class to some better name (say sdk::logs::LogRecordData).
• Add setter for observed_timestamp in sdk:logs::Reordable and sdk::logs::LogRecordData.
• Similar to Span's Recordable, add a getter method for LogRecordData in Recordable class. This can be eventually implemented by all it's derived implementation (not in scope for now).

  /**
   * Get the LogRecordData object for this Recordable.
   *
   * @return LogRecordData*
   */

  virtual explicit operator LogRecordData *() const { return nullptr; }

This would let us avoid having ReadWriteLogRecord class. This method can be potentially used inside LogRecordProcessor to filter the logs based on it's contents (not in scope for now).
