> Our current dataset.registerTempTable does not actually materialize data. So, it should be considered as creating a temp view. We can deprecate it and create a new method called dataset.createTempView(replaceIfExists: Boolean). The default value of replaceIfExists should be false. For registerTempTable, it will call dataset.createTempView(replaceIfExists = true).
