Version 8.0.0 

Enhancements

• The ICU library files that are installed with the Linux version of the product have been upgraded to version 74.1. In addition, the ICU library file names have changed. For the 32-bit driver, the ICU file name has changed from libivicu28.so to  libivicu.so. For the 64-bit driver, the ICU file name has changed from libddicu28.so to libddicu.so. This upgrade is available starting in build 08.02.0965 of the ICU library files.*
• The installer program has been enhanced to support Azul Zulu JRE 11. As a result of this change, the installer has ended support for platforms that do not support Java SE 8 or higher. The installer supports the following operating systems after the enhancement:
  • Windows 8.1 or higher
  • Windows Server 2012 RC2 or higher
  • UNIX/Linux: Any operating system on a machine using a JRE that is Java SE 8 or higher (LTS version), including Oracle JDK, OpenJDK, and IBM SDK (Java) distributions.
  Important: These changes do not affect the operating system requirements of the driver.*
• The driver has been enhanced to fall back to JSON query format when the arrow format is not properly initialized. The driver uses a high-speed arrow transfer that requires the restricted APIs from java.nio package. When the JVM is not correctly configured for Java SE 16 and higher, an exception is returned when the driver executes a query. To allow you to continue executing queries in this scenario, you can configure the new Arrow Fallback To JSON (ArrowFallbackToJson) option to switch to the JSON query format. Refer to Arrow Fallback To JSON for details.*
  Available: Driver version 08.00.0100 (B1193, U0945, J001002)
  
• The drivers using base version B0649 and later have been enhanced to include timestamp in the internal packet logs by default. If you want to disable the timestamp logging in packet logs, set PacketLoggingOptions=1. The internal packet logging is not enabled by default. To enable it, set EnablePacketLogging=1.*
• A Password Encryption Tool, called ddencpwd, is now included with the product package. It encrypts passwords for secure handling in connection strings and odbc.ini files. At connection, the driver decrypts these passwords and passes them to the data source as required. See Password Encryption Tool (UNIX/Linux only) for details.*
• The driver is enhanced to support the COPY command for loading and unloading 
  data from local file systems and cloud storage platforms. Refer to Using COPY command for details.* 

Changed Behavior

• The product package no longer includes the ODBC Cursor library file (odbccurs.so) because it has some known security vulnerabilities that could potentially expose you to security risks.*
  Note: The installer program cannot remove the ODBC Cursor library file automatically while installing a new version of the driver. Remove it manually.
• The installer program has been updated to no longer install common components for drivers that do not use them. As a result, the installer program no longer installs the following common components for the Snowflake driver:*
  • OpenSSL library files, such as ivopenssl30.so, ddopenssl30.so, fips.so, and openssl.cnf.
  • Curl library files, such as libivcurl28.so and libddcurl28.so.

  If the files are not used by any other DataDirect driver on your machine, you can safely remove them from existing product directories.

Features

• The driver serves as a complete pass-through driver. It leverages the Snowflake SQL engine to execute queries.
• The driver provides enhanced performance over the native ODBC Snowflake driver.
• The driver supports create, read, update, and delete operations.
  
• The driver provides proxy support. Refer to Connecting through a proxy server and Connection option descriptions for details.
  
• The driver supports the handling of large result sets with configurable paging using the Fetch Size connection option. Refer to Fetch Size for details.
