Read #

Table store with Spark 2.4 does not support DDL, you can use the Dataset reader and register the Dataset as a temporary table. In spark shell:

val dataset = spark.read.format("tablestore").load("file:/tmp/warehouse/default.db/myTable")
dataset.createOrReplaceTempView("myTable")
spark.sql("SELECT * FROM myTable")
