 class SnowflakeOperatorAsync(SnowflakeOperator):
     """
-    Executes SQL code in a Snowflake database
+    - SnowflakeAsyncOperator uses the snowflake python connector ``execute_async`` method to submit a database command
+      for asynchronous execution.
+    - Submit multiple queries in parallel without waiting for each query to complete.
+    - Accept List of queries or multiple queries with ‘;’ semicolon separated string and params. It loops through the
+      queries and execute the query in sequence. Uses execute_async method to run the query
+    - Once a query is submitted, it executes the query from one connection and gets the query id from the
+      response and passes it to the Triggerer and closes the connection (so that the worker slots can be freed up).
+    - The trigger gets the query id list as input and poll every few seconds to snowflake and check
+      for the query status based on the query id from different connection.
+
+    Where can this operator fit in?
+         - Execute time taking queries which can be executed in parallel
+         - For batch based operation like copy or inserting the data in parallel.
+
+    Best practices:
+         - Ensure that you know which queries are dependent upon other queries before you run any queries in parallel.
+           Some queries are interdependent and order sensitive, and therefore not suitable for parallelizing.
+           For example, obviously an INSERT statement should not start until after the corresponding to CREATE TABLE
+           statement has finished.
+         - Ensure that you do not run too many queries for the memory that you have available.
+           Running multiple queries in parallel typically consumes more memory,
+           especially if more than one set of results is stored in memory at the same time.
+         - Ensure that transaction control statements (BEGIN, COMMIT, and ROLLBACK) do not execute in parallel
+           with other statements.
