26 | * This unique ID is assigned to mysql when the connection is opened and is | |

28 | * | |
29 | * The intent is that it is available for logging purposes and for triggers. | |
30 | * | |
31 | * The resulting string is 17 characters long. This consists of 13 characters of uniqid | |
32 | * and 4 more random characters. | |
33 | * | |
34 | * Uniqid is unique to the microsecond - to make it more unique we add 4 more characters | |
35 | * but stop short of the full 23 character string that a prefix would generate. | |
36 | * | |
37 | * It is intended that this string will be saved to log tables so striking a balance between | |
38 | * uniqueness and length is important. Note that I did check & lining up with byte values | |
39 | * (e.g 16 characters) does not confer any benefits. Using a CHAR field rather than VARCHAR | |
40 | * may improve speed, if indexed. | |
