-----------------------------------------------
Summary: Switch persistence identifiers to UUID version 7
Key: SYNCOPE-1720
URL: https://issues.apache.org/jira/browse/SYNCOPE-1720
Project: Syncope
Issue Type: Improvement
Components: core
Reporter: Francesco Chicchiriccò
Assignee: Francesco Chicchiriccò
Fix For: 3.0.1, 4.0.0
As pointed out by several resources (for example [this blog
post|https://vladmihalcea.com/uuid-database-primary-key/]), UUID version 4 are
not particularly suitable as primary key identifiers, mainly because of their
[random
nature|https://en.wikipedia.org/wiki/Universally_unique_identifier#Version_4_(random)]
which can cause issues with B-Tree database indexes.
As pointed out, a better solution is to use [UUID version
7|https://www.ietf.org/archive/id/draft-peabody-dispatch-new-uuid-format-04.html#name-uuid-version-7],
time-based UUID bit layout sourced from the widely implemented and well known
Unix Epoch timestamp source.
