 States are a key concept in SDF. They hold a simple value or they can be divided into multiple partitions based on a key.  Each partition state can have many different types.  
 
 One of the type is `arrow-row`.  For example, follow snippet define state `count_per_word` that store each row into arrow dataframe.

 The SQL is executed in the context of all the available dataframes, so you can perform any JOIN or complex SQL operations with them. Each dataframe is represented as a table, and each table name is their state name replacing hyphens(-) with underscores(_) as illustrated below.
