Progress DataDirect for ODBC for Apache Cassandra Driver

    An asterisk (*) indicates support that was added in a hotfix or software patch subsequent to a release.

    Refer to the following resources for additional information:

    • Product Compatibility Guide: Provides the latest data source and platform support information. 
    • Fixes: Describes the issues resolved since general availability.  

    Version 8.0.0

      • 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 support connection failover and client load balancing when connecting to a cluster. You can enable this new functionality by specifying a comma-separated list of member nodes using the new Cluster Nodes (ClusterNodes) connection option.
        Available in driver version 08.00.0216 (B0706, U0505, J000324)
      • 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.*
      • The driver has been enhanced to support the Duration data type, which maps to the SQL_VARCHAR ODBC type. Currently, the Duration type is supported only in simple columns, and not in Collection types.*
      • The Driver Manager for UNIX/Linux has been enhanced to support setting the Unicode encoding type for applications on a per connection basis. By passing a value for the SQL_ATTR_APP_UNICODE_TYPE attribute using SQLSetConnectAttr, your application can specify the encoding at connection. This allows your application to pass both UTF-8 and UTF-16 encoded strings with a single environment handle.
        The valid values for the SQL_ATTR_APP_UNICODE_TYPE attribute are SQL_DD_CP_UTF8 and SQL_DD_CP_UTF16. The default value is SQL_DD_CP_UTF8.
        This enhancement is available in build 08.02.0449 of the driver manager.
      • The driver has been enhanced to support all the data consistency levels for read and write operations that are supported by Apache Cassandra data stores. Data consistency levels are configured using the Read Consistency and Write Consistency connection options. Refer to the user's guide and reference for descriptions of these options.*


        • Supports SQL read-write access to Apache Cassandra data sources.
        • Supports CQL Binary Protocol.
        • The driver supports the core SQL-92 grammar.
        • The driver supports all ODBC Core functions and some Level 1 and Level 2 features.
        • Supports user id and password authentication.
        • Supports Cassandra data types, including the complex types Tuple, user-defined types, Map, List and Set.
        • Generates a normalized view of Cassandra data. Tuple and user-defined types are flattened into a relational parent table, while collection types are mapped as relational child tables.
        • Supports Native and Refresh escape sequences to embed CQL commands in SQL-92 statements.
        • Supports Cassandra's tunable consistency functionality with the ReadConsistency and WriteConsistency connection options. 
        • Supports the handling of large result sets through the FetchSize, NativeFetchSize, and ResultMemorySize connection options.
        • Supports applications that do not support unbounded data types through the ASCIISize, DecimalPrecision, DecimalScale, VarintPrecision, and VarcharSize connection options.
