Gets the DataFrame's current storage level.
Returns
StorageLevel
Notes
On serverless compute, storageLevel is DISK_ONLY while the DataFrame is cached and NONE otherwise. See Cache DataFrames on serverless compute.
Examples
df1 = spark.range(10)
df1.storageLevel
# StorageLevel(False, False, False, False, 1)
df1.cache().storageLevel
# StorageLevel(True, True, False, True, 1)
df2 = spark.range(5)
df2.persist(StorageLevel.DISK_ONLY_2).storageLevel
# StorageLevel(True, False, False, False, 2)
