Hey Team, I was reading through the dagster-snowflake documentations and saw that for the snowflake io manager we don't need to specify the input manager key when we are trying to read from snowflake nor do we need to do it in the resource_defs when we are using it to write into snowflake. I was wondering why this was the case when compared to standard io manager documentation and what is the current "standard" way to write into snowflake from dagster.

Ahh I think i found the answer to my own question: "The I/O manager that's used for handling a particular op output is automatically used for loading it in downstream ops."
