Found insidePushdown is not possible in all situations. For example, Spark UDFs cannot be pushed down to Snowflake. Similarly, Presto supports federated queries. After the staging table is created, Spark SQL connector copies the data into the staging table, and then Snowflake runs the query against the source tables and inserts it into the target table, as shown in the following images. While it does have isolated tenancy like Snowflake, it currently only runs on AWS. The statistics are collected by Snowflake and retrieved by the connector. Snowflake offers powerful SQL capabilities via query pushdown thereby enabling data transformation to a more effective ELT model. Pushdown Optimization (PDO) can significantly improve performance by pushing query processing to Snowflake when Snowflake is the Spark data source. Well, that's all for now. they have big query omni coming which is multi-cloud but it'll probably be a while before it's comparable to big query in gcp.
