Hi team, how does Pinot encode byte columns to display on the UI? Are they encoded as hex strings?

Yes, they are encoded as Hex strings.

/**
 * Converts the byte array to a Hex encoded string.
 *
 * @param bytes byte array
 * @return Hex encoded string
 */
public static String toHexString(byte[] bytes) {
  return Hex.encodeHexString(bytes);
}

Ah, danke 🙂
