UUID V1 Orderer

Ordering UUID V1 bytes by inserted timestamp for practical purposes. If you want to store UUID's sequentially in databases, you can use this library.

Requirement

Go 1.14 ~ 1.15, other versions not tested

Instalation

Add it in your project: go get github.com/MufidJamaluddin/uuidv1_orderer

How to Use

1. Ordering Existing UUID's

unorderedUuid := UUIDStringToBytes("c5db1800-ce4c-11de-a5e2-1b45123c6e98")

orderedUuid := ToOrderedUuid(unorderedUuid)

orderedUuidStr := UUIDBytesToString(orderedUuid)

// next, your logic

2. Transform Back to Standard UUID V1

orderedUuid := UUIDStringToBytes("11dece4c-c5db-1800-a5e2-1b45123c6e98")

standardUuidV1 := FromOrderedUuid(orderedUuid)

standardUuidV1Str := UUIDBytesToString(standardUuidV1)

// next, your logic

Notes

The differences explanation between ordered and standard UUID V1 is bellow

UUID V1 In String

Example: c5db1800-ce4c-11de-a5e2-1b45123c6e98

Meaning:

1. Timestamp 1de-ce4c-c5db1800 in c5db1800-ce4c-11de
2. Standard UUID version 1 in c5db1800-ce4c-(1)1de
3. Clock sequence a5e2
4. Standard MAC Address or Nonstandard Random IDs 1b45123c6e98

Ordered UUID V1

Reorder timestamp to it's origin form with UUID version on top.

Example: 11dece4c-c5db-1800-a5e2-1b45123c6e98
