What

Records can be inserted into snowflake using a standard SQL INSERT statement or by first copying the data to blob storage (e.g: azure, gcs, s3, snowflake internal) then using the COPY command to read that data into snowflake. The staging approach is an order of magnitude faster and should pretty much always be used except for the smallest data volumes/proof of concepts.

The snowflake destination currently supports staging to S3. it should also support internal staging as described here: https://docs.snowflake.com/en/user-guide/data-load-considerations-stage.html

How

Workload :
CREATE STAGE @TEMP_STAGE_NAME
PUT file://local/some_folder/* @TEMP_STAGE_NAME.
COPY FROM @TEMP_STAGE_NAME
DROP @TEMP_STAGE_NAME

Standard Inserts 3 millions records
snowflake_insert_3m
Internal Staging 3 millions records
snowflake_int_3m_7

Recommended reading order

  1. x.java
  2. y.python

The test failure does not look relevant to this PR. The issue should have been fixed already on the master branch. Maybe you just need to merge master and the build should pass.
