Streams are a key model component. They represent a structured store of data within PhixFlow receiving data from one or more components, processing it then storing it.

| Field | Description | ||||||
|---|---|---|---|---|---|---|---|
| The number of days data to keep in the stream. When an archive task runs for a stream, all stream data is deleted if it is at least Keep for X Days old or if it is older than the Keep for Y Stream Sets most recent valid stream sets. If both Keep for X Days and Keep for Y Stream Sets are set, stream data will be deleted only if it meets both conditions. If neither are set, stream data is kept indefinitely. If Save Archive to File is ticked, deleted items are first saved to archive files. The age of data in a stream set is its 'to' date relative to the 'to' date of the newest valid stream set in the stream. See here for how to set up and schedule an Archive Task. Please see the section below on Archiving Examples toalso
| ||||||
| Keep for Y StreamSets | The number of stream sets data to keep in the stream. See Keep for X Days for the main description of archiving. | ||||||
| The number of days for which to keep superseded data in the stream. If Track Superseded Data is ticked, then this field will become visible/enabled. In a stream where the superseded date is tracked, the stream data will contain a mixture of superseded records and "active" records - that is, records that have not been superseded. When an archive task runs for a stream, records that were marked as superseded more than Keep Superseded for X Days days or more than Keep Superseded for Y Stream Sets stream sets ago are deleted. If both Keep Superseded for X Days and Keep Superseded for Y Stream Sets are set, superseded records will be deleted only if they meet both conditions. If neither are set, superseded records are not deleted. This means, for example, that if you have set Keep Superseded for X Days to 4, you will be able to roll back 3 days, making the 4th day the latest valid day. If Save Archive to File is ticked, deleted items are first saved to archive files. Please see the section below on Archiving Superceded Examples to see how this value can be used within Archiving strategies. | ||||||
| Keep Superseded for Y StreamSets | The number of stream sets for which to keep superseded data in the stream. If Track Superseded Data is ticked, then this field will become visible/enabled. See Keep Superseded for X Days for the main description of archiving superseded records. | ||||||
| Save Archive to File | If Save Archive to File is set, archived data will be written to compressed archive files before being deleted. | ||||||
| Apply Archive Filter | If this flag is ticked then a dialog box appears within which a filter can be created. This filter will be applied during archiving and only the records which match the filter will be archived and deleted. |
