Snowflake is a data warehousing service in the cloud.
Use Snaps in this Snap Pack to:
Insert, upsert, update, unload, execute and delete records in Snowflake.
Query a particular Snowflake instance and returns the requested records or keys.
Execute multiple queries.
Enable SCD2 type historization.
Supported Versions
This Snap Pack is tested against Snowflake Cloud version 5.29.1(JDBC driver version: 3.13.1). User-defined functions (UDFs) created in the Snowflake console can be executed using Snowflake - Execute and Snowflake - Multi Execute Snaps.
During execution, data processing on Snaplex nodes occurs principally in-memory as streaming and is unencrypted. When larger datasets are processed that exceeds the available compute memory, the Snap writes Pipeline data to local storage as unencrypted to optimize the performance. These temporary files are deleted when the Snap/Pipeline execution completes. You can configure the temporary data's location in the Global properties table of the Snaplex's node properties, which can also help avoid Pipeline errors due to the unavailability of space. For more information, see Temporary Folder in Configuration Options.
Requirements
Snowflake JDBC jar 3.1.0 or higher (Tested and supported for the JDBC jar version 3.12.3).
We recommend you to use the latest version of the Snowflake JDBC jar driver (version 3.13.1) if you are experiencing slow or hanging execution when using Snowflake Snaps, as this is a known issue with an older version of drivers [Ref : https://github.com/snowflakedb/snowflake-jdbc/blob/master/CHANGELOG.rst].

Stable
Enhanced the Snowflake S3 Database Accountto skip batch execution, when the Batch size value is one. When the Batch size is greater than one, the batch is executed.
Added the following truncate options to Snowflake - Bulk LoadSnap to truncate existing data before performing data load to more efficiently transfer data where possible.
Truncate data: Truncates existing data before performing data load.
Truncate columns: Truncates column values that are larger than the maximum column length in the table.
Fixed an issue with Snowflake InsertandSnowflake Bulk LoadSnaps where the schema names or database names containing underscore (_) caused the time out of Pipelines.
Added support for all existing Snowflake Snap accounts to connect to a Snowflake instance hosted on the Google Cloud Platform

4.20 Patch
db/snowflake8800
Latest
Certifies the Snowflake Snap Pack against JDBC Driver version 3.12.3.
Snowflake Execute and Multi-Execute Snaps may break existing Pipelines if the JDBC Driver is updated to a newer version.
With the updated JDBC driver (version 3.12.3), the Snowflake Execute and Multi-Execute Snaps' output displays aStatusof "-1" instead of "0" without theMessagefield upon successfully executing DDL statements. If your Pipelines use these Snaps and downstream Snaps use theStatus field's value from these, you must modify the downstream Snaps to proceed on a status value of -1 instead of 0.
This change in the Snap behavior follows from the change introduced in theSnowflake JDBC driver in version 3.8.1: "Statement.getUpdateCount() and PreparedStatement.getUpdateCount() return the number of rows updated by DML statements. For all other types of statements, including queries, they return -1."
