We are using this to querying by composed row key. For example row key is defined like: 2 bytes of salt (eg. modulo of ID) +  8 bytes of ID + 8 bytes timestamp. In Phoenix is row key mapped to columns id and date, so queries looks like:

```
SELECT * FROM t WHERE id = HEX_TO_BYTES('240f7e0f3806fe80300001')
```
