Query Execution 2021-07-26, QE 2021-08-09, QE 2021-08-23
Is there a way to determine what exactly was changed on the nested field of the document?
One of the fields in my document is "branding" (shown below). If a change occurs to a single field under "branding", the change stream will return an entire "branding" object and there is no way to know which exact sub-field was affected.
"branding": { "control_panel": { "primaryFont": { "name": "c713b99e-40d4-4d31-629a-6def5f7963c6.ttf", "displayName": "Arial", "fileType": "tff" }, "secondaryFont": { "name": "c713b99e-40d4-4d31-629a-6def5f7963c6.ttf", "displayName": "Arial", "fileType": "tff" }, "companyLogo": { "name": "18c0c0ef-5d4c-4a3e-b16c-a8f640c3e2be.png", "displayName": "1200px-Logo_NIKE.svg", "fileType": "png" }, "backgroundImage": { "name": "8d1cc393-0132-4a3f-9b2a-d5a9a68bd4e4.jpg", "displayName": "s23-slams_original-web", "fileType": "jpg" }, "primaryColor": "ffffff", "secondaryColor": "ffffff", "primaryFontWeight": "bold", "secondaryFontWeight": "regular", "publishSchedule": "AUTOMATIC", "publishScheduleStatus": "UNPUBLISHED", "videoRecording": "DEFAULT", "videoRecordingLink": null, "hideVideoRecording": false, "hideMeetingReplay": false }, "registration_page": { "openRegistration": "15", "proxyWebsiteLink": null, "termsAndConditionsUrl": null, "title": "New Event - test copy", "description": "" }, "pre_event_page": { "message": "", "lobbyMessage": "", "musicOption": "DEFAULT" }, "thank_you_page": { "title": "test event", "description": "" }, "post_event_page": { "meetingDetails": "" } },
This makes change streams useless unless I apply custom business logic and store all the changes and then perform JSON diff myself.
Is there a better way?
