Question
Partially purge data from a text field
We have a history field used to store web page activity, which is then displayed in our real-time alerts:

It’s a text field (not string) and looks like this in the Marketo:

Even though this is a text field, over time, this may reach its limit by active, known users on our website. Any thoughts on how to go about partially purging old data – let’s say ‘older than 6 months’ – while leaving the rest of the data intact?
