Summary

Adds the ability to configure custom (granular) deletion policies for posts for specific teams and/or channels. When the daily retention job runs it selectively deletes posts by age based on the configuration.

Request:

Code Block
{
    "team_idids": ["z7rxbxbfb7yxdydxzi8pestath"]
}

Response:

Code Block
{
    "success_ids": ["z7rxbxbfb7yxdydxzi8pestath"],
    "failure_ids": []
}

Because a teams can only be associated to a single granular retention policy, we must specify which teams failed.

...

DELETE /api/v4/retention_policies/:policy_id/teams/:team_id removes a team from a retention policy.

Model

  • Rename DataRetentionPolicy to GlobalDataRetentionPolicy

  • Add RetentionPolicy representing a record in the RetentionPolicies table.

  • Add RetentionPolicyChannel representing a record in the RetentionPoliciesChannels table.

  • Add RetentionPolicyTeam representing a record in the RetentionPoliciesTeams table.

...

  • Reactions

  • Preferences (of Category ‘flagged_post’)

  • Threads

  • ThreadMemberships

  • LinkMetadata TBD: these aren’t currently purged via data retention, but they probably should be.

FileInfo (and their associated files on disk) and ChannelMemberHistory continue to be deleted system-wide with no new granularity.

TBD: Why is ChannelMemberHistory currently deleted as part of message retention days settings?

Mobile

No changes. Existing file-deleted and post-deleted UX covers all.
