How to extract name of Primary Key Columns of feature store table in Databricks environment ?

[NSRBX]

Hello,

Please suggest how to obtain name of primary key columns in my feature store table in hive metastore.

'describe' gives me the name of the columns but not the indexes

Thanks in advance for your help.

In the delta, there are no primary keys (so far). Feature store is just a normal delta table so you can do all operations as for normal tables.

Hi Vidula,

Yes, I solved the query !

I used the function getTable of class FeatureStoreClient(). You have all datas you need : primary keys, timestamp_keys, features of feature store table.
