OpenPDC historian retentions

Hi, openPDC historian has retention policies for saving data to a database ?

For example, auto deleting older rows since new one is coming. I have to do my own retention based on the database that I use or there are a configuration parameter that I dont see ?


Hi Andre,

It sounds like maybe you are using the AdoOutputAdapter to write real-time data to a SQL database using openPDC? That adapter does not have any options for automatically deleting data. This could perhaps be implemented using a custom adapter, but we don’t have any such adapter built in that can be used to automatically delete data from a SQL database based on a retention policy.
