I have a synapse spark spool as well as a blob storage gen 2 .
usually I use Access key and use
spark.conf.set
to set the access key everytime the notebook run .
how to make it a persisted config of the spark pool , so that I don't need to include spark.conf.set everytime for the spark session ?
apart from Access key , can we use Service Principal or Managed identity to authen to blob inside Synapse Spark ?
there is tab call credential , and see we reference this credential store from Synapse spark
