13 This page describes how to enable and configure the collection versioning feature on the API server.
17 There are 2 configuration settings in the @Collections@ section of @config.yml@ that control this feature.
21 # If true, enable collection versioning.
22 # When a collection's preserve_version field is true or the current version
23 # is older than the amount of seconds defined on PreserveVersionIfIdle,
24 # a snapshot of the collection's previous state is created and linked to
25 # the current collection.
26 CollectionVersioning: false
28 # This setting control the auto-save aspect of collection versioning, and can be set to:
29 # 0s = auto-create a new version on every update.
30 # -1s = never auto-create new versions.
31 # > 0s = auto-create a new version when older than the specified number of seconds.
32 PreserveVersionIfIdle: -1s
35 Note that if you set @CollectionVersioning@ to @false@ after being enabled, old versions will still be accessible, but further changes will not be versioned.
