Analyzing queries and troubleshooting with Snowpark Java
To inspect the evaluation plan of a DataFrame, call the explain method of the DataFrame. This prints the SQL statements used to evaluate the DataFrame. If there is only one SQL statement, the method also prints the logical plan for the…
Quick reference: Snowpark Java APIs for SQL commands
This topic provides a quick reference of some of the Snowpark APIs that correspond to SQL commands. (Note that this is not a complete list of the APIs that correspond to SQL commands.)…
Python and Java support for serverless tasks
Serverless tasks can invoke the following object types and functions: user - defined functions (UDFs) and stored procedures written in Python, Java, and Scala. You can use Python or Java in your tasks in a few different ways.
Java requirements for the JDBC Driver
The Snowflake JDBC driver requires Java LTS (Long - Term Support) versions 1.8 or higher. If the minimum required version of Java is not installed on the client machines where the JDBC driver is installed, you must install either Oracle Java…
Key pair authentication failure due to ObjectIdentifier() or SecretKeyFactory not available errors
CAUSE: It is possible that the security toolkit used to generate the encrypted private key used for key pair authentication uses an encryption schema that is not compatible with a Java runtime version's native encryption libraries.
Reading files with a Java stored procedure
You can read the contents of a file with handler code. The file must be on a Snowflake stage that’s available to your handler. For example, you might want to read a file to process unstructured data in the handler.
Emitting trace events in Java
You can use the com.snowflake.telemetry.Telemetry class in the Snowflake Telemetry API library to emit trace events from a function or procedure handler written in Java.
Logging messages in Java
You can log messages from a function or procedure handler written in Java by using the SLF4J API. When you’ve set up an event table to store log entries, Snowflake stores log entries generated by your handler code in the table.
Creating a Session for Snowpark Java
To use Snowpark in your application, you need to create a session. For convenience in writing code, you can also import the names of packages and objects.
Accessing data from a Java stored procedure
To access data with a stored procedure handler written in Java, use the Snowpark library APIs. When handling a call to your Java stored procedure, Snowflake creates a Snowpark Session object and passes the object to the method for your…
