how much time does it take to re-align identity graph

[itsMeTechy]

how much time does it take to re-align the identity graph, when a profile enabled individual profile dataset is dropped. when there are 1.2 million profiles are impacted.

also, when the same 1.2 million data is re-ingested into another profile enabled dataset (from the same schema) how much time does it take to re-align the identity graph and bring those 1.2 million identities back into the profiles.

we have a situation which requires to re-ingest the data and profile needs to re-built for those data.

Thanks

Hi @itsMeTechy ,

The time required depends on how the data is re-ingested, how the mapping is configured, and the current platform load among other factors. Rebuilding the profiles can take anywhere from a few hours to several days.

Hi, @itsMeTechy,

I imagine, from your question that you deleted and ingested the data one after the other without waiting. In this case, the processes will happen as following:

1. The platform will delete all the data from the dataset (generally very fast, few minutes)

2. Ingest all the data from the new dataset, also pretty fast. 

3. Re-evaluate all the profiles in the Profile Snapshot Dataset. As I understood, the data didn't really change, so the profiles will be the same, nevertheless, it does not mean that the profile fragments are going to be the same, thus in order to update the profiles you requiere a dataset evaluation. That takes 24h aprox. Generally, this happens every day at a certain hour depending on your configuration.

Also, it might happen that the platform will first delete all the profiles and then, in the next snapshot evaluation it will create them once again. Make sure to first enable a dataset to profile before ingesting all the data, otherwise it won't be qualified as profile data.
