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. -- This message was sent by Atlassian Jira (v8.20.10#820010)
