What are Link Correlation Keys present in the LinkExtended.hbm.xml?

I have observed that LinkExtended.hbml.xml contains the following entries. Could someone help me understand about them?


Link correlation keys.
There are a fixed number of these but you may need to adjust their
sizes and indexes.
The maximum size of an indexed string on SQL Server is 450.  
If you are not using SQL Server you may raise this.
-->

    <property name="key1" type="string" length="450" index="spt_link_key1_ci"/>
    <property name="key2" type="string" length="255"/>
    <property name="key3" type="string" length="255"/>
    <property name="key4" type="string" length="255"/>

Hey @SandilyaKrovvidi,
Thanks for posting! I have reached out to one of our Solution Architects regarding your inquiry. They should be able to provide you with some additional insights here shortly.

Thanks for that. I will wait for your response.

Hey @SandilyaKrovvidi,

I wanted to give you an update and let you know that we are still working on your question. Those are not used very often, if at all, and there is not currently any documentation available on them. We are going to try to reach out to some of our “Old Guard” employees to see if someone can shed a little light for you.

Here is what we have learned: This is old code. They were mostly used for correlating unstructured data and activity from collectors, i.e. the correlation before FAM.

If you wanted, you could use those keys for other functionality - they are enabled using this:

I hope this helps; thanks for posting again and I hope you enjoy the rest of your week!

Thank you so much for all your efforts @jordan.violet :slight_smile:
