You can enable up to 100 objects for a single org.
You should add all required objects to the
enabled objects list; this ensures objects are pushed to History Stream as efficiently as possible. GRAX continuously writes files for each object as capacity becomes available.
The format for the folders looks like this:
parquet/org=1234/object=myObject/day=nn/hour=nn. New folders are be added in your storage bucket for each version/modification based on the date/time that the object/version was backed up, following the same format, always based on UTC time.
Folders are only created for hours that contained data updates/changes; if there are no updates to an object in any given hour, no folders or files are created for that hour.
The size varies based on the amount of and size of the data, but users should expect a range of 10MB-40MB per folder/file.
Why does the record count for an object in History Stream not match the record count shown in Auto Backup?
For backup, the numbers are split up into "records" and "versions." For History Stream, the number of records and versions is combined in the “total records written” number. Please keep in mind that there might also be a small discrepancy between the totals if an object is still catching up in History Stream. Additionally, if you had records backed up via Legacy Backup, those numbers are not included in the Auto Backup totals but are shown in the History Stream numbers.
How do I rewrite an object in History Stream if new attributes have been added or field permissions have been updated?
You can reset the object for Auto Backup within the “Tools and Diagnostics” page within the “Settings” tab. This re-runs the data for that object so updated versions are captured and subsequently added to your History Stream files. This does not remove the previously written data from the parquet files, and duplicates any records that were already written and which are still present in the GRAX dataset.
Should I continue to run Auto Backup and archive jobs while objects are being enabled for History Stream?
Yes, GRAX is designed to have all these tasks run concurrently without diminished performance.
There are many variables to the speed including the amount and size of data, available CPU, other app activity, etc. There is no set time frame for how long writing an object (or objects) takes as this is determined by specific factors within each org.
History Stream speed is dependent on various factors such as the size and quantity of objects. There is no action that can be taken to increase the writing speed, but GRAX is continuously working to maximize efficiency of this feature.
Functionality that needs to scan backup data (Global Search, archive jobs, ect…) might run a bit slower than usual, but there should not be any noticeable difference or related errors.
Customers must have at least the minimum requirements for GRAX as defined here. This allows History Stream to run as intended, but having better CPU and RAM resources improves speed and capacity.
Yes, you can remove objects from the enabled list to pause History Stream for a specific object. Once those objects are added back to the enabled list, History Stream picks up where it left off. This might be useful if prioritizing certain objects or if internal flows need to be adjusted.
