sql_hook_params parameter, and the behavior should stay the same.

4.0.2¶
Breaking changes¶
Note
This release of provider is only available for Airflow 2.3+ as explained in the Apache Airflow providers support policy.
The SnowflakeHook is now conforming to the same semantics as all the other DBApiHook
implementations and returns the same kind of response in its run method. Previously (pre 4.* versions
of the provider, the Hook returned Dictionary of { "column": "value" ... } which was not compatible
with other DBApiHooks that return just sequence of sequences. After this change (and dependency
on common.sql >= 1.3.1),the SnowflakeHook returns now python DbApi-compatible “results” by default.
The description (i.e. among others names and types of columns returned) can be retrieved
via descriptions and last_description fields of the hook after run method completes.
That makes the DatabricksSqlHook suitable for generic SQL operator and detailed lineage analysis.
If you had custom hooks or used the Hook in your TaskFlow code or custom operators that relied on this
behaviour, you need to adapt your DAGs or you can switch back the SnowflakeHook to return dictionaries
by passing return_dictionaries=True to the run method of the hook.
The SnowflakeOperator is also more standard and derives from common
SQLExecuteQueryOperator and uses more consistent approach to process output when SQL queries are run.
However in this case the result returned by execute method is unchanged (it still returns Dictionaries
rather than sequences and those dictionaries are pushed to XCom, so your DAGs relying on this behaviour
should continue working without any change.
UPDATE: One of the unmentioned, breaking changes in the operator in 4.0 line was to switch autocommit to False by default. While not very friendly to the users, it was a side effect of unifying the interface with other SQL operators and we released it to the users, so switching it back again would cause even more confusion. You should manually add autocommit=True to your SnowflakeOperator if you want to continue using it and expect autocommit to work, but even better, you should switch to SQLExecuteQueryOperator.
In SnowflakeHook, if both extra__snowflake__foo and foo existed in connection extra
dict, the prefixed version would be used; now, the non-prefixed version will be preferred.
The 4.0.0 and 4.0.1 versions have been broken and yanked, so the 4.0.2 is the first change from the
4.* line that should be used.
