When writing a dataframe with an array column, the value is saved as a string in the form of a "WrappedArray(x, y, z)". Since Redis supports nested data structures through RedisJSON, spark-redis could offer a way to store complex spark data structures.

root
 |-- my_array: array (nullable = true)
 |    |-- element: string (containsNull = true)
 |-- id: string (nullable = true)
